The key to Lallybroch is more significant to Jamie than Claire, and he never takes it well when he can’t protect the people he loves.
Whatever happens for them in the aftermath, neither will likely have a very clear head when it comes to Bonnet.
My money is on Claire being more pragmatic about it.
Given that this particular plot twist went down differently on the show than in the fourth book in Diana Gabaldon’s saga, I can’t say if one of them will take Bonnet’s theft better than the other.
