I don't know that 1world is confirmed innocent unless I missed something. He's just given us a scenario in which it is quite likely that we will kill a mafia.
If Mort is mafia, things are pretty simple, with the low chance that 1world is also mafia and they are trying to make everyone think 1world must be innocent.
If Mort is not mafia, either 1world or his source are mafia.
While I am still suspicious of you (Terro) and Annele, I feel it best that we get this sorted out before we rely on my behavioral analysis to lynch people.
Edit: Also, chances are high that either 1world or I will be killed by the mafia tonight if Mort or 1world's source are mafia. If there are any abilities out there that can save someone from mafia kills, I'd advise using it on one of us. If it is Mort, they would kill one of us since we both know the player that is Phase Spider. If it is 1world's source, they would want to try to keep this "source's" identity a secret. The good thing is that since we both know this person, the will definitely be revealed in this scenario unless they can kill us both.
