Overall it was a good episode. Not their best but still good.
Espo was surprisingly awesome. Loved Ryan for calling him out on being a jackass though
At the end with that transit cop I was a bit worried that Espo would have dumped Lanie because she had what he wanted- an instant family. But glad that didn't happen.
The case was just okay to me.
And Caskett- loved the rings and loved the Turner/Houch stuff. And Beckett playfully shoving Castle and giving him her sexy smile
And so far it seems that Beckett is still 'Beckett'
