For those of you who don’t really like the theory that the Hostess is responsible, I may have figured out another possibility.
This is a fair point. However, we don’t know who these people are, and nobody would confess to having one. However, it is public knowledge that Hermes does have a weapon from the Week 3 HOH. Before you ask, proof is below.
It wouldn’t be a stretch to guess that Hermes’ weapon was the one used to kill TE. Why TE? Because TE chose not to use the veto. Hermes could’ve wanted to target somebody else that week who wasn’t initially nominated, and this could be his way of getting back at TE.
As for NP being the one on the floor, something that should be considered is that NP was the person that Hermes placed his faith in throughout Week 3. I’m not sure if this is another hint left by the Hostess, or if NP was possessed and was the one that actually killed TE, but both of those imply that Hermes is responsible. And Hermes can’t even throw in his input in helping solve this. I know that he was the last HOH, but maybe he already knows the answer, and maybe that’s why he can’t contribute in the flavor.
