Castle and Beckett’s Separation Takes a Literal Turn in “The Blame Game”

By Geannie Bastian

This week's episode was all about separation anxiety – and I'm sure many a Castle fan would tell you, anxiety over separation is relatable. But the fake up was kind of on hold this week. Instead, Castle and Beckett found themselves literally separated by a killer seeking revenge on his parents.

That's because the parents used their adorable twin kids as lab rats in a psych study. And, well, it didn't go well for the kids. Our killer became a recluse and his sister killed herself. It was the death of the sister that set off her brother's madness - though surprisingly, since were talking about separation anxiety, no one mentioned that the brother becoming a recluse might have had an effect on his sister's mental state. Because that couldn't be relevant, or anything.

Obviously the best plan to expose his parents' rather abusive choices was to kill the woman trying to expose what they had done – because that didn't go far enough – and then kidnap 3 couples to stand in for all the people who let the kids down. Obvious to a mentally unbalanced killer, anyway.
