In Papyrus' case, having a friend to back you up and to talk to is actually really relieving. Even if it can't truly fix the problem, it feels nice to escape the world or just simply relax a bit. Undyne really is a good friend. ^^
This page makes me feel good knowing that Undyne's there to support Papyrus. But also worse knowing that this situation is much bigger and more intangible than anyone here, even Undyne. *sigh* the struggle is real
You never truly understand how much someone's support can help you until its freely given. Most people don't know they need it until they have it and it's like the world is just a bit brighter.
As someone who spent a lot of time alone, I definitely understand the relief Papyrus feels. To have someone who will stand by you and help when you need it is one of the most special things one person can grant another.
Even though the end left a feeling of unease, I actually teared up a bit from gratitude to Undyne.
For Pap to know that he has another person in his corner, that's only ever been kind and supportive, for him to realize he doesn't have to shoulder the world, it just makes me so happy for him. Just imagine the relief he must feel. Now he can be there for Sans in a better mind sight which will help the both of them. :)
