I know this is a weird thread, so just as a disclaimer, it doesn't have to involve romantic interests.
What I'm talking about is that if you think that _____ could be related to _____(as in sibling, parent, or other), post it here and why. For example, I think that Yu could be related to Chris, just sayin'.
So, please post why you think whatever, and please keep this thread appropriate. Post away!

If this counts for Zero-G, I would say Mal likes Zero, I know it's weird but she seems to always blush when he wins or something.

This will be full of fangirl speculations based on nothing but personal wishes, so no, this does not deserve a topic.
