I read in an interview with Brad William Henke that in a deleted scene he finds out the tattoo that his prison 'boyfriend' had was actually fake.

Actually they showed her having a vision from everyone else's perspective once before - I think when she, Ravi, and Major were digging looking for those bodies with the U inside.

Just thinking out loud here, but what if Ravi didn't come up with anything; there's always the chance that he 'knows' Blaine is faking? (I only say because, like you said, it is so completely implausible that Ravi could have come up with some memory drug at all, let alone this quickly).

Yep he ate a piece of pizza with brain on it and asked if there were mushrooms - he doesn't like the texture. I guess mushrooms and brains have a similar texture!

I think it makes total sense as well: The vic was a don at mindfulness. Clever!
