For Becky's subplot, it's the kind that just makes you want to curl up in a fetal position and wish the world away. I just felt bad for all the parties involved. It's a tough thing to go through at such a young age, with different sets of pressure pushing and pulling at you when faced with this situation.
Some don't like the Becky character, but I don't really have a problem with the Becky character, I think the writers just "felt" her character, and something organic came out of what they saw in Madison Burge's portrayal through the early episodes, and they just ran with it. Sometimes, that's how break-out characters just happen on a show, even with casting other more "reliable" talent, like Jurnee Smollett.
Anyhow, a solid dramatic episode, without the histrionics, just emotional turmoil simmering underneath a facade. Sad stuff. FNL has always been able to do the hard episodes without going over the top, and retain a feeling of genuine human emotions seething through the characters.
