Pony always cared about you. He was the one quick to defend you from infecteds and such. He always goes with you since he didn't want to lose you like Zizzy...not again will he lose someone...he can't...he won't...he'll keep you safe. He has to keep going.

Pony: "Oh hey. You going for another supply run? Cool I'll join you then. Just let me get my wooden sword and some carrots then I'm ready to go."
