I came up with this Joker styled plot since I now have two explosives. Lets assume Rhea dies.

I plant the explosive on Airlea, one of the more loved people in the group. I then explode her and blame Hobert. Meanwhile, I plant my other explosive, the one which detonates when I die on Hobert. I tell Hobert everything. That I planted an explosive on Airlea and exploded it to frame him and that the defensive item I got was a different explosive. I then tell Hobert that if he reveals what I did and I die, he dies as I have planted the second explosive on him. Now only Peter and I know Hobert has the explosive. Imagine the chaos that would ensue?

Just a random evil idea. I wonder how it could be improved more...

Omg I just came up with another plan... Assuming Rhea dies and I had Ari's knife. Even better:

I plant the self-imploder on Hobert. Plant the explosive on Airlea. Give Hobert the detonater. I then inform him I have Ari's knife. I give him 24 hours to blow the explosive or ill kill him and once he is dead I will reveal he has the detonator and planted it on Airlea and I just saved her making me the Hero. I will then tell Hobert the self-imploder is on him so if the group lynches me, he dies. So he has a choice. Kill Airlea or lose his life trying to prevent it. If he kills Airlea, I would then kill him.

For the record, I wouldn't do these even if I was evil... way to short term. If I was suicidal it would be fun thoe.
