Nick Brain is not currently in a relationship, and to the best of his knowledge, he has not fathered any children with the few "ladies of the night" he has been with over the years.

Nick Brain does have a very close relationship with both his parents (Martin and Jolene Brain). For their respective Parent's Days, he paid off the repairs and restoration for his dad Martin's dope ass vintage Chevrolet Corvette, which got mildly sideswiped by some drunken idiot Calgary Dragons fan, and for his mom Jolene, he bought a vintage feather and quill and inkwell writing set, along with vintage Queen of England stationery, and a silver tea set engraved with Buckingham Palace emblems of some description (all of which were gifts from the Queen for winning IIHF gold for the UK a while back). Jolene appreciated the Mother's Day gift, being one of those people randomly obsessed with the Queen for some reason, and Nick was happy that his parents were happy.
