When Jordan got frozen, I kept thinking that the Bat-team should've called Caitlin Snow at STAR Labs. Who understands cryogenics better? Ryan may not have met the other heroes yet, but Luke was probably aware of them through Kate, and if he has a friend at ARGUS, which is where Diggle and Cisco now work, then he has that connection too. (I wondered if his friend at ARGUS could be Diggle, but he said an "old friend," while he only met Dig a few months ago.) So... Mary got stabbed by a Poison Ivy thorn. Any bets on whether Ivy's consciousness takes over her body? Her insight about a plant cure could be the first sign. Normally I'd be annoyed by the hugely overused trope of a person of average physical strength being able to instantly kill someone by a head twist to snap their neck (the idea of which deeply disturbed me before I learned it didn't actually work). Not only would it take far more strength than someone of Rachel Skarsten's build is probably capable of, but it wouldn't even be fatal; at worst, it might cause paralysis. But I'll give it a pass since it was Alice's delusion and she could've just seen too many movies and TV shows that use that stupid cliche.
