The show is very good and I think he's fairly different from the comics version, anyway. Mercy will be able to confirm or deny this for me haha hen she comes in because she's read them as well as seen the show and I think we all know I know nothing about comics in general lol.
He is a pretty quiet boi who likes the moon and writes poetry about how pretty the moon was and was his dad's #1 because Reg is an asshole who numbered them in terms of "usefulness". He was the loyal one who stayed when everyone else had left, but he's never been socialized much outside of his siblings so he doesn't know how to people and will be quiet and awkward a lot outside of his siblings and whoever he/they happen to bond with.
I think he could potentially get along with just about anyone but I do think he and Bellamy have quite a bit in common.
