I think the notable thing is that Jake
didn't use the drug on Megan or Sarah. There were two details that indicated that Jake can't use the pills for some reason. The first being the fact that he puked it up almost immediately after leaving the basement scene, but that could have also been nerves. The second and more notable detail being the fact that during the weeks of MC's coma and recovery, Sarah is not under Jake's thrall. And given that Sarah likely would have been Jake's first target, it's safe to assume Faith probably isn't enthralled either, though she is subject to Jake's blackmail and abuse.
I'll bet he's spent the past month trying to get the pills to work in futility, and he'll probably try looking for a buyer once he figures he can't get them to work. Though a funny spin would be if Faith took a pill and Jake's been under her thrall the entire time.
And I disagree about the length of time in the Hospital. I thought it wrapped fairly reasonably and MC recovered rather quickly considering how badly he was beaten. The episode had less tension than the last episode but it still had plenty of things going on.
