I would be too sure on those two. I've been weary about Tyler because he was allowed to stay, and because triplemo's role was never killed or revealed...
Also, what about Jlap's hypothetical role makes him innocent?
Tyler was host-confirmed to be town I thought? And jplap's ability is confirmed (by Goomy RIP), and is far too powerful to be a scum role. I mean I guess it could be, but if the host are giving those sort of powers to the mafia we're boned regardless. I have played previous games with this role (off-site), and the theory behind it is that it should be used to build a safe space away from mafia eyes, but can be infiltrated if the additions are not chosen correctly.
