I wouldn't say I like them, but I enjoy the
characters of
Skittles and the
Gatekeeper, because you see them so briefly yet you get that tingly feeling that they are going to play a much larger part in the later seasons/chapters.
I'd like to think Skittles becomes more than just a Deus Ex Machina type character and evolves into something always overlooked and underestimated but ultimately sacrifices himself to save the day in a major way.
The Gatekeeper is just too creepy and evil not to return in a major way. I dread and look forward to that day.
