This episode was something of a transition episode, reminding us of old characters and accelerating the Jacobite plot back in Scottish territory. In all, I'm pretty happy with it.
Cons:
There was a bit of a problem with this episode, and that's that it felt slightly disjointed. The first few scenes are at Lallybroch, and then after that we jump to Lord Lovat's estate, and by the end of the episode we're off to join the uprising. A lot happened in one episode, and there didn't seem to be a seamless connection between all the different parts. One thing I generally admire about this show is its ability to keep an episode thematically tied together, even if a bunch of different things happen in it. I didn't feel much of that thematic resonance here.
Also, Laoghaire makes a reappearance in this episode, in a total departure from the books. Basically, she ends up at Lovat's estate as a maid for Colum. She apologizes sincerely to Claire, and then later Claire uses her to try and soften up Lord Lovat's son and get his support for the uprising. In the end, Jamie thanks Laoghaire for her assistance, at Claire's insistence, and we see that Laoghaire still has dreams of winning Jamie's love. Okay... I don't mind Laoghaire being weaved back into the story here. In fact, I find the actress really likable, and I get the need to see her again and reintroduce her character to the story so that viewers will remember her when she becomes important later. But this plot thread presented a rather unbalanced image of her. She seems truly repentant, but then in the end she's still scheming to win Jamie from Claire? And Claire's behavior was a little unbalanced, too. Are we meant to see Laoghaire as a scheming evil bitch who tried to have Claire killed, or a lovesick girl who didn't know what she was getting involved in, and truly feels bad? Claire's reactions to her seem to vacillate between these two very different things.
