Actually she's rarely been in Wakanda in the last ten years. I meant they could've met up in some other random place he was visiting. Turn on the news, see Amani, that sort of thing. :D But yeah, she grew up half in the NA area, so whenever Kitty came to New York, they would've probably gotten together.
Yeah, she mostly ended the relationship because Owen wasn't ready to get help yet and she couldn't be that close to him as it got worse. But she's been publicly supportive of the need to destigmatize mental health problems whenever she got asked a question about dating him (bring a princess, it got around, even though they were just in high school).
