Father Gabriel entered the new season as public enemy Number 1. "Oh, I really like the priest guy," said no Walking Dead fans, ever. He was cowardly, and whimpered away into the background, something that could be expected of an unstable person during such a catastrophe. But his freak-outs weren't localised to just his character, they'd directly put everyone else in danger, and despite being saved countless times by Rick's group, Gabriel STILL insists on sneaking to Deanna about them. He was a truly dire character in Season 5, though Season 6 has began with a repentant, sincere Gabriel, willing to learn and grow into the group. A lot hinges on his 'training' with Carl. If he does come good, great. If he slips back into his old self, it's time to go.
