Tobi added you to a GC.

Deidara: "Tobi, what the hell is this?" Sasori: "I don't have time to be in pointless GCs like this..." Kakuzu: "Me neither, I don't want any part of this." Hidan: "Yeah, seems pretty lame." Pain: "This is childish." Itachi: "I agree with Pain, this is so naive." Konan: "It really is." Kisame: "Oh, but maybe this could be fun." Zetsu: "..." Tobi: "You should all be more optimistic about this, like Kisame! This GC can be very fun!"
