Don't take this too seriously, please. This is just some marital problems that I imagine these canon couples might have in the long run, all marriages go through some kind of issue at some point, and a lot of them are a testament to how strong the relationship is. Based on what I know from what the film's have shown us, this is what I imagine would happen with each of them:
Married couples argue. It's not a huge secret, EVERY couple fights. And sometimes it's about something really trivial and pointless. But couples will still fight because that's how relationships work. People are annoying, and we piss each other off sometimes. It doesn't mean the love isn't there, it just means that we need a little space from time to time. Marriage is a lot of work. It requires communication, compromise and understanding of one's needs and desires.
We didn't really see much of Mufasa and Sarabi's marriage, so i chose them to represent this reality. Considering that Sarabi does seem like a stubborn character, and Mufasa has a pretty short temper, i'm going to guess that these two used to fight a lot. But the love was definitely there.
A less common reality than arguing, but still a very common marital problem. When one (or both) spouses have to work a lot, it can often leave the other feeling alone and neglected. This can cause depression and anxiety in the sufferer. But with the proper help and communication, this problem can be fixed. One just has to identify the problem, before it gets worse.
I chose Simba and Nala for this, because while we do see their marriage more than the other two; they don't really do much together. At least not in Simba's Pride. Nala virtually disappears in the second one, only appearing to recite incorrect wisdom and support Simba by...standing in the background. Yeah, i'm not a huge fan of what they did to Nala in the sequel, she's pretty useless and I don't particularly enjoy that (but i digress). Simba seems to spend most of his time and energy running the kingdom and obsessing over Kiara's safety. So, it wouldn't surprise me if Nala began to feel lonely, I certainly would.
Don't hate me for this. It's a known fact that one in three marriages ends in divorce. Sometimes the person you're with; will leave you. It'll be heartbreaking, and it won't be fair, but that's life sometimes. There were three unions/marriages in TLK: Mufasa & Sarabi were separated by death, Simba & Nala were still together by the end of the second movie, so who does that leave? Yup! Kiara and Kovu. You could argue that they didn't really get married at the end, but there was some kind of union ceremony and most fan fiction writers say that they do, so I'm going to say they got married too.
Now, before you bite my head off; I didn't choose Kiara & Kovu for this just because I dislike them (which I do), I actually have good reasons to think that it'll end this way. First of all, their age. Kiara and Kovu if they were human, I'd say they'd be about 16-18 years old (in human years). That's a little too young to get married. At this age, we aren't fully matured yet; emotionally or physically. Young people, especially young guys; aren't ready to settle down at that age, they still have a lot of testosterone and need to experience their young lives at the fullest. To settle down that young?? Not fricken' likely! Yeah, Simba & Nala were young too, but not THAT young. You can tell by the size of Simba's mane compared to Kovu's, Simba's mane was full, Kovu's was not. So I'd say Simba would have roughly been in his 20's or so when he and Nala reunited.
Secondly, Kovu's upbringing. Kovu was raised to kill, Zira filled his heart and soul with hate and anger. That's something that can't be fixed in an instant, not even 'love' can erase the damage that Zira had done. He was no less than brainwashed from early childhood. Any and every psychologist will tell you that; to overcome brainwashing is a long and complicated process, and is sometimes irreversible. Zira damaged him, to the point of no return. Kovu wouldn't know how to be a good partner, it's not like he even had a father figure either. Through little fault of his own, Kovu would be naturally/instinctively aggressive and abusive due to his upbringing. Yes, it's a kids movie, obviously they just ignore this fact of basic psychology, and I'm NOT suggesting they should show this as it is. But I'm just further stating my claim as to why Kiara and Kovu are doomed.
Thirdly, what would stop him from leaving? Aside from Simba probably killing him, and having nowhere to live if he did. But really, Kovu has no real obligation to stay. If Simba is still in charge, Kovu could just up and leave. Simba and Nala needed to stay together, they were to rule the Pride Lands as King and Queen once Scar was pushed off the throne. Then they had a child together, and a long history, so together they stayed. But really, if Kovu left the Pride Lands while Simba was in charge, they could just find another suitor. It wouldn't be fair to Kiara, but that's how it would work.
Plus, to me; Kiara & Kovu are the weakest TLK couple in the franchise (despite nearly the entirety of the sequel being dedicated to their romance). Mufasa and Sarabi's relationship was pretty down played, but you could still see the love they obviously had together before they were divided (and likely reunited) by death. Simba and Nala spent most of their childhoods together, and no doubt developed a strong bond. They were separated by tragedy, reunited by a bizarre coincidence, fell in love, banded together, threw Scar off his throne and took back their land. They had a child, and worked together to ensure the life of the Pride Lands. Kiara & Kovu roughly had a similar circumstance, but much MUCH weaker. They only knew each other for less than two days before 'falling in love'. Picking up a Pocahontas vibe right here! Yeah yeah, they stopped the war between the families and united the prides, but i just didn't feel the connection between them. All i can really think about when watching them are 'High School sweethearts'. Yeah, they look cute together, but you can't help but think that it most likely won't last for more than a few years. There are exceptions of course, but they're very rare.
Before you comment telling me how 'wrong' I am about Kiara & Kovu, could you separate your personal preference for me? Don't base your opinion around how much you like these characters, if you like them, that's fine! But try and see my point of view from a logical standpoint, if Simba & Nala were more likely to divorce, I would acknowledge it. But the odds really are against Kiara & Kovu, whether you want to admit it or not.
