Amazing opening and ending, at the expense of the kinda slow and long middle part of the episode. DeVoe being a leisurely undefeatable villain reminded me of a similar scene from Legion. Also shows just how much he thinks about "being found out" when he broke his cover just to attack people for having wrong taste in music.

Caitlin plotline, IMHO, is most interesting.

Meta DNA has been established as able to "hide" until triggered by a traumatic event in DC universes, similarly to Mutant genes in Marvel works.

Caitlin's mom probably knew about it all along, explaining her strange attitude regarding "research" of her daughter when she started turning. In fact, if Caitlin was subconsciously trained to repress "Killer Frost" since childhood to the point that she has forgotten about it, it can explain why it ended up developing into a whole split personality (when originally she was just turning emotionally unstable).
