We all know Medical is phenomenal at the PPC, capable of reviving canons killed in fics and, while short of outright resurrection, healing up Agents spectacularly. Though with all its technology, is it capable of reversing things from various canons that are stated to be impossible to reverse?

Here's an example scenario: Agent Whatsisface (DMS, Bleach Division) is pursuing Mia Esplendissima, pink-haired Negative-First Espada and TWU WUV of Ulquiorra Cifer, through the halls of Las Noches when he bumps into Hueco Mundo's lord, master, and wearer of very stylish coats, Sosuke Aizen, and is hypnotized.

Now, it is stated many times in Bleach canon that Aizen's hypnosis is irreversible; once he gets you, he controls everything you see from then on. Obviously this would be a risk to the PPC, but could Medical correct it? More importantly, should they? Would reversing something irreversible cause weird things to happen?
