I'm not sure I believe Rush, Kenny faking info is one thing especially if this is a recurring thing but that is a little convenient. Still if he is lying why say you switched with Mikey? Hopefully we can make some sense of this after night.
of course i am, why else would i be so confident that Kenny can't have tracked me to Lawls?
You could have an untrackable/unwatchable scum role like in Fallout where one scum group had that advantage though it's more likely you have the actual role you've claimed though that isn't an alignment tell since busdriver can go either way.
So if Rush is telling the truth about his role, which is most likely the case due to the risk in lying since I'm sure there are other roles in this game that could catch that lie, Kenny is a confirmed liar who should be ignored for the rest of the game. If Kenny had real results, he would have gotten Mikey visiting Lawls. Mikey appears to have a day role and has confirmed Dan as Town. Doc has confirmed Skyfall (not sure how) as Town as well.
Anyway, Rush could easily be a bus driver AND have killed Lawls. I'd have thought Kenny would track him to more than one person then. Kenny should 'ask' magic about that. Also does Magic typically notify you if you're re-directed? I thought I remember a re-director type role in DBZ, i didn't play though.
