I enjoyed it. Definitely not the best. Didn't really do much to move the season plot forward but gave some needed character development to the side characters.
My predictions for Wells and the prison is he wants all the villains there and will release them at once for some reason or another at the end of the season. Maybe that will necessitate the need for the full CW Justice League or super team up (Arrow, Atom, Flash, Firestorm, New Canary, Katana, etc).
