The Xlaw thing, he claimed Vanilla town in your game too when he was Lumine. I feel like claiming vanilla is a good way to get by and explain not having actions to report for town. Sure as you said he might get caught by a watcher or tracker but we dunno what kinda abilities scum can have. I mean we have Ekko out here tanking a lynch lp in a majority setup.
The Cal thing, id think he would be more informed if scum right. To me his cluelessness and overall attitude in the game ( like him claiming you were town a bit earlier) strikes me as that of someone who doesnt have the help of teammates keeping him updated.
