I'm on a time crunch, so let's rapid-fire this baby.
Cons:
Things I do not care about: Owen and Teddy. Whatever. There's this cutesy little plot thread about Teddy losing her engagement ring, and it turns out Leo swallowed it... I think it's all supposed to make me think they're oh-so-adorable, but ugh... nah. I'm not feelin' it.
Samesies with Amelia and Link and all the baby daddy drama. Link is right that Amelia screwed up and should have realized sooner. And he's not wrong for wanting to know the paternity. I just really wish this whole conflict was a thing that did not exist... isn't Amelia settling down and having a kid with Link enough of a story on its own?
Apparently now we're going to have to watch Catherine and Richard go through their relationship woes... yawnnnn. I've always disliked Catherine, so I'm not really looking forward to this story-line.
The vaping PSA is something I totally agree with, but I don't think there's a way of doing a story like that without it feeling a little bit after-school-special. Not unwatchable by any means, but still.
