This episode was awesome, another part of the arc of Johnny vs Stillson doomsday vision. It was sad that Alex have to die at the end and it looks for nothing because Malcolm apparently have his research. And as I mention before is interesting to see Malcolm's character more in the critical parts above Stillson supposedly doomsday. In all Johnny's vision the doomsday happen with Stillson as President but I wonder as I say is he's being manipulate by Malcolm. Definitely looks like Malcolm have his personal agenda and is using Stillson to get it.
The episode was just totally interesting, great story, arc continuation and more intrigue. Definitely one of the best.
