I don't watch the 2016 reboot so I'm worried to know what "has a more...supportive relationship with his cousin gwen" means. Especially considering that the original series was bad enough in that department (though at least it could be chalked up to not originally being related when the show was in development). The reboot would have no excuse.
gwen isn't snarky with him like she was in the original
instead she's generally a lot more patient and willing to support him
