I've been told that I have that effect on people.
Perhaps I can help? I know that if I were in your position I'd want to get to know the person who has a child with my best friend.
So, perhaps, you could start with a question such as, "Can you tell me something about yourself?" or perhaps you could even ask, "has Jack mentioned how much you resemble a friend of ours?"
To which I'd most likely respond with something along the lines of this: "My name is Helen Magnus and I was the Head of the Sanctuary Network in my universe. And yes, it has been mentioned how much I resemble one of your friends."
