Giant Dancing Hedgehogs are Nightmare Fuel

There are several scenarios that Pete suspects to walk in on when he arrives back at the hospital:

Scenario 1: Vegas is still asleep and Macau and Tankhun have somehow managed to remain civil towards each other. This seems like the least likely scenario.

Scenario 2: Vegas is still asleep and Tankhun has tied Macau to a chair for the hell of it. While this would cause a great amount of trouble, it is almost comforting in its normalcy.

Scenario 3: Vegas has woken up and spilled every single secret that he has in his drugged up state, leaving him even more vulnerable than ever.

Scenario 4: Macau has killed Tankhun in a fit of grief stricken rage, which causes Arm, in turn, to kill Macau in a fit of grief stricken rage, since Arm and Tankhun are apparently in love and Pete can't stop thinking about it.

Scenario 5: Tankhun has verbally attacked drugged up, pod person Vegas, which has caused him to burst into tears and pull out his IV, in hopes that he bleeds out.

It's none of those things. Those things would be expected. Nothing happening right now is expected.
