Yeah, I noticed the failed hug too.

We know Mercury and Emerald aren't blood related (He says "You want me" to her) and it doesn't seem like Torchwick and Mercury are related, based on how they treated each other...

My guess is that they see Cinder as a mother figure, although she's not actually related to either of them. Mercury and Emerald seem like evil Ren and Nora.
