It was a little weird when I first saw it, but mostly because at the time I didn't know what happened with Tom. The more I thought about it, you two are a good match. Two sexy badasses who've lived the Doctor-infused life. See? Someone you can share those secrets with.
Honestly, though, why wouldn't I be okay with it? I'm in another dimension, it isn't like I'll be running in to stop the wedding. And he deserves more than me. All I ever did was let him down. He's better than that.
