Anders + Panacea/Vengeance
That part of the movie where Bones uses that pill after lecturing Scotty is hilariously a great example of how the Enterprise crew logics their way out of things. idk if you remember, but after Bones asked him what the heck he was doing, Scotty essentially responded, "But what if this is how it was invented??" And I would bet that Bones, in a split second, used that same logic for the pill scene. Yay time loops!
