Despite coming from different times, living under different circumstances, and leading different lives, this was one area in which Claire could relate to John.
Even if Frank doesn’t appear in Season 4 in the flesh, he’s still on Claire’s mind (and his ring on her hand).
As if Claire hasn’t already dealt with enough heartbreak during her time!
I particularly enjoyed the scene when John was feverishly confessing that he simply couldn’t love his late wife the way she deserved, and he still burns with love for Jamie.
