I don't actually enjoy being a hater about this show as much as it might seem that way! Sigh.
Cons:
I watched this episode with a friend (hi) so she heard my commentary about certain things and we were both in agreement that Lucas in this episode was... it was too much. Up until this point I had really praised the story-line with Katie, I thought it was sweet, and Lucas was still being annoying like he always is but it felt like his annoying-ness was built into the narrative, with Bailey trying to temper his behavior and them working through this situation together as Katie went from getting better to dying. I liked that nothing explicit had been mentioned about there being a romantic vibe between the two of them, but it was plain to see if you were paying any attention. It was all working for me.
