Safest option to me looks liking voting for Doddsy, it will also give us infos about Adam. Remember, Adam is VERY sure about Doddsy! If Doddsy flips scum we can trust Adam, if Doddsy flips town Adam would look very bad. Why would he take such a high risk if he wasn´t sure that he caught a maf?
Doesn´t matter much to me that Gramma might also be scum, Doddsy is the one who needs to get resolved imo.
Ekko and TAC are unlikely to be in a team and one of them I´d say is scum, this is what I would assume.
