@Background Pony #CC06
Depends on the execution as with all things related to storytelling. If that is all he will be good for then it would be better for him to not appear often. Ultimately, Sunny should have more going for her than just being inclusive about who she’d be friends with. I mean, she needs to be a naturally charming character for her to befriend anyone at all - even if we are talking about another earth pony like her.
That said, I do wonder how Hitch is her only real friend in Maretime Bay despite her being an uplifting character to be around, in my opinion. In fact, she strikes me as someone who can get more ponies on her side if just because she could get other ponies attached to her. Izzy, Zipp and Pipp following her to Maretime Bay just to stay friends does allude to this, you know?
