Having a child raise an infant seems like an interesting idea for a story (And from what I know of some of the endings to The Walking Dead: Season Two by Telltale, it is), but at some point, someone is going to end up looking like a (Hmm, let’s be polite…) massive jerk. Mostly because it’s a horrible decision.

Not helping that Anderson bungled it up big time.

This comic is the exact reason why Lauren Faust’s original concept of Celestia raising Spike is so much better and why I follow it. She also stated that they (Celestia and Spike) have a mother-son relationship, with Spike calling her mom or mommy when they’re alone.
