As far as I know, no one saw or talked to her that morning except MOE and Howard and Moe said he stuck his head in the door and saw her moving around in the bed.
It could have been an "ILLUSION" if Howard was near the bed kinda tucking her in. Remember, she did not speak to Moe.
I think Howard was near the bed and Moe said he was going to breakfast to Anna AND HOWARD.
So who could this mysterious someone else be who snuck into Anna's room and gave a very weak, doped up, sleeping person a massive dose of cr**.
Damn you Howard, you're trying to create another ILLUSION.
You're the little kid who kicks another kid and says, it wasn't me, he's lying and gets away with it.
Yes, that is what Moe told us BEFORE he (we assume) began cooperating with authorities. So whatever he said in the beginning was under HKS's direction. So maybe there was no movement at all by Anna.
