I can't see Clive being Mafia with also absorbing powers from both town members and mafia members with such a low powered town. But I can see Clive being a town soft lynch pin and being a backup net for helping the town as they successfully lynch, or lose power roles.
So from my PoV this is Flower, since Michelle is mechanically clear, and I cannot rationalize Clive as a member of scum with this setup.
Flower's claimed actions from yesterday also make no sense, so it's just a process of elimination on my end.
