I guess that was the side effect of the new drug. Seem like it's a stimulant that make him more energized for a while like when you drink a godly amount of energy drink, but it come crashing down when the drug effect is over.

But I wonder if ML going to help the MC properly or will he just keeping him attach like a pet.
