Gal is an odd character in the crew. One could've said his head is always up in the clouds, if his real passion wasn't for the stars themselves. He's certainly a pacifistic dreamer but a reliable navigator and a sympathetic friend.
Though he doesn't particularly get along with Uriah in the sense that the other's batshit attitude puzzles and concerns Gali, he still recognises that he has much to learn from the seasoned traveller and is shaping up to be a decent spiritual successor.
