Love, lust, you name it or else there's no story. Eventually it runs into TV tropes territory.

Especially when you compare Gwen to the typical leading lady. I'll take Kate Beckett interrogation scenes over Gwens hissy fits anyday.

Well it was getting a little crowded when Rick got Lucy. The system for his smarthouse. While Kate was away. I think Kate put Lucy in the fridge because she was being rude to her.:D

Maybe Ianto could offer coffee to Esposito and Ryan. In their very own spinoff. A girl can dream.:)
