As fun as it would be to go full super turbo autist and dig through every single piece of old footage of Monty that can be found, I'm not going to because I don't hate myself (or RWBY) quite that much. That said, I'm damn near 100% positive that somewhere, someone asked Monty early on if there were any plans for romance in the series or for any of the main crew, and Monty said "No, that's not the focus of the series, and I don't think I'll ever add that".
I like romance shit, it can be fun, but I was actually happy hearing that Monty didn't want that for his series because RWBY was supposed to be a fun action/adventure series, and I thought romance would bog it down. So, I'm confident when I say Barbara is a lying whore, and this Bumblebee shit exists purely as a surface level attempt at trying to attract/appease viewers so the ship sinks a little less slowly.
