>>107995279The twelve Alternian trolls likely aren't all friends, they're compatriots banded together for a common purpose. When that purpose is removed, their personal strifes and drama flare up and devolve into infighting. Like, Sollux and Eridan were by no means friends, Karkat just got them to stop fighting each other for the moment.
So it seems likely that
Karkat and Terezi are friends
Karkat and Sollux are friends
Sollux and Terezi are friends
Karkat and Kanaya are friends
Terezi and Vriska are friends
Karkat and Gamzee are friends
Nepeta and Equius are friends
Sollux and Aradia are friends
Feferi and Sollux are friends
Eridan isn't really friends with anyone.
And I'm not sure who Tavros was friends with.
The kids were all friends, even if we never saw Rose talk to Jade. The trolls not so much.
