they do become friends.
heck they (the 3, gara, temari, and kankuro) become friends with shikamaru.
their really good people.
also gara says he owes it to konoha, and that he now understands the whole "Love" thing.
no matter who you love (weather good or bad) aslong as you have that emotional string with them you will do what ever to have them happy.
he talks some bs like that to Lee. it was kinda funny reading that part. lol
