Longshot and jet friendship headcanons?
Even though he is aware of Jet's flaws, Longshot respects/admires him and loves him like a brother. Jet loves and trusts Longshot and wants to do right by him.
One reason Longshot felt comfortable with Jet from the very beginning was because Jet never pushed him to speak when he didn't want to
When Longshot first joined the group, Jet tried to "teach" him a variety of weapons to find his perfect match. When they figured out that the bow & arrows were meant for him, Jet cheered loudest of everyone!
Jet can read Longshot's facial expressions extremely well (even though he doesn't always listen)
Jet always laughs at Longshot's "jokes"...even when Longshot wasn't joking
Longshot has surreptitiously kept Jet from walking off a tree branch and falling to his death about a hundred times; Jet has never noticed this and probably will never notice this
