"Nefela, I have a question for you. Maybe you've already mentioned something about this, but I can't go into detail right now, it's extremely difficult for me to interrupt our conversation for Mafia. In short, don't you find it strange that Tox is trying to establish a connection with you? Don't you see anything suspicious about it?"


I don't see anything suspicious about it.
In my opinion, Tox isn't trying to establish a connection with me; he's using the exact same tactic to connect with Gumer, defending him.
And yes, before the game started, one of his arguments, along the lines of "Nefela, join the game, there's a special role just for you," was "I'll help you avoid being eliminated for inactivity."
