This is kind of an odd tweet and may be meaningless, but I thought I'd post in case someone else gets it. I don't think it's a reference to Brenchel. I'm wondering if it's a Big Brother reference I don't know because I don't follow that show.
I have some bad news for you Amazing Race fans: Brenda & the Witch are running in season 20.

It could be a reference to them because Rachel is kinda the 'man' in the relationship... so
Brenden --> female form --> Brenda,
and a lot of people think Rachel is a *itch, so thus, witch...
but those are only expressed by a few certain people. I was glad Rachel won BB.
