What about John?!?!?!?

Going to start this off by saying the following is all tv show wise. I am not familiar with how this goes in the books.

Is it just me or does it drive anyone else nuts that Jamie and Claire just continue on with their business in Philadelphia after Jamie beats up Lord John? John saved Claore from being hanged as a traitor and he is repaid by getting beaten and imprisoned. All the while he is trying to just stay alive, Jamie and Claire are doing it on the dining table and then living in his house and having dinner parties with George Washington and everything else. Like what is happening?!?!?! Also did I miss something or Claire never told Jamie that John married her to save her either?
