So, was watching the 23th episode when discovered there was no 24th. Shame! Was really expecting one more. Well, spoilers ahead.
For once, the season does not end with Beckett or Castle dead or disappeared. Only a small doubt on Kate future. On the season 6 finale, the explanation was not good. I think more could be done. But that was OK.
Other than that, I just expected Molly C. Quinn (Alexis) to be more active in the series. She is so cute and beautiful…
