Dude, in season 1 both Chance(T-Bone) and Jake(Razor) has a crush on Callie but she had more scenes with Jake/Razor, so it was a pairing was in the making already. I felt like in season 2, the introduction of Felina was a great addition to the cast. She was a strong, action lady who followed her own moral code more than her orders. And immediately I felt like she resonated with the Swat Kats but specifically Chance(T-Bone) because they were the same, while Jake was no less of a hero than Chance, you always knew that Chance is the more stubborn one, the more reckless one, the more insubordinate one and Felina was exactly like that too.
This is why if pairing ever comes to question, I'm calling it: Jake x Callie, Chance x Felina.
And woulnd't you just burst out laughing at Farel's face if he sees them together?
