Rachel Nichols as Rachel's mom? Nice! I haven't seen her since Continuum and I always had a thing for her :3
Sadly, this episode was the weakest, so far. Rachel freely roaming around the place after they noticed she had escaped was ludicrous. They would have put guards at the door of each of the rooms where the other Titans members were being held, immediately. Also, it's weird that a shady place like that wasn't packed with guards everywhere. Also also, it's even weirder how Dick shook off the drugs that quickly, when he was tripping big time just a few minutes earlier. Everything was just too convenient.
The acting and action scenes were on par with previous episodes, but the writing was dismal in this one.
