Well, let me begin my review of Outlander 7.10 by saying there will be spoilers galore in what I have to say about this powerful episode.
And let me add another reminder that I have yet to read any of the Outlander novels, so I have no idea how the story this TV adaptation is based upon unfolded and progressed.
And I'll also add that I have a firm principle that if you don't see a character's head blown off in a TV series or movie, there's a fair chance the character has not been killed, regardless of what anyone else says or does.
So, with all of that in mind, let me say that I don't believe for a moment that Jamie died on that ship which went down and on which "all hands were lost". There are more than a few explanations of what really happened, and resulted in Claire receiving that terrible report. The ship didn't really go down at all, and the report that it did is some kind of ruse the English or the Americans are perpetrating on behalf of their war effort. Or, if the ship did go down, Jamie was in fact not on it. Or, if he was indeed on it, he survived after all -- probably the most likely explanation, which would account for why they didn't find his body, alive or dead.
I'm sure we will see Jamie sooner or later walk back into Claire's life. Of course, she'll be a married woman by then, because she'll of course agree to marry Lord John Grey. Because Claire has confidence in what her heart tells her, that Jamie is still alive, and marrying John is the best way to protect herself and her future with Jamie.
Meanwhile, it's good to see young Ian -- now the only Ian -- back with the new love of his life. And it's fun to see how Roger is doing in the past, meeting other time travelers and other-aged-versions of characters he has come to know in his various travels through time and space. This looks to be moving into one of the most powerful second half of seasons in the series so far.
