Hee. In the X-men/Teen Titans one-shot, Kory all but jumps Peter's bones when she discovers that he speaks Russian, and while that may have generated tension for Peter and Kitty, you can see that Kurt has no such reservations. Of course, for Kory it's all about language acquisition, but in the non-poly-friendly 80s, you can see how that might not have been so perceived.
