Hiccup knows another loner when he sees one, and appreciates his courage under fire and all. If Jamie hadn't kept a cool head through his panic and gotten them free from the aliens, Hiccup would've probably been on the ship or still on the planet when the alien popped and would be dead right now.
He's been trying to reach out to Jamie as best as he can, but isn't quite sure how to break through his shell and still being kinda unsure of himself and having self esteem issues in general, he's not sure if Jamie's just antisocial or not interested in being his friend.
He plans to keep trying, though, and even if they don't hit it off as friends, still wants him to realize he's a friendly acquaintance he can turn to for help or favors or anything he needs. He's not sure if they have the personalities to be friends, since he's having trouble getting to know what Jamie's is, but he does want him to not feel alone or isolated.
