Not the most exciting episode, but plot points were presented and the storyline moved forward as needed. The addition of the love potion bit was interesting; it presents the idea that Laoghaire knows Jamie finds her attractive but doesn’t love her. (In the books, she is convinced he loves her.) I can’t help but speculate that she might mention the love potion when they get to the trial. It also shows that, as of right now, Claire still feels nothing more than friendship for Jamie, and Laoghaire knows it.
The use of 1940’s music was jarring, but appropriate, especially in conjunction with Claire’s voiceovers; this is all what’s going on in her head, and why wouldn’t she find herself sometimes humming familiar tunes?
