2 SK's In One Game

[Metroidude]

After a search of the forums, I couldn't find any topics about there being 2 Serial Killers in one game.
I once played a game where I was Serial Killer, and there were 4 people left. 1 town, 1 SK, 1 GF, and apparently another SK. He claimed that "Hey other SK I'm SK too, you should help me lynch GF and we win together".
But I went on to lynch the "other SK" because I figured my role card said that I had to be the last one alive to win, right?
I was curious as to what would've happened if there were just 2 Serial Killers alive at the end of the game. Would they both win?

yes. In a troll game once where there were 1 mafioso and 4 sk. The sk killed the mafioso and won.

SK's don't necessarily have to win alone.

SK's can win with other SK's and survivor/witches.

Arson can also win with other Arsons and survivor/witches.

Please don't mix it up on later games, it can make the other SK/Arson pissed.
