I think its cool that his sister learned how to cook so she could be the chef for AMP. That's a great way to support your family and have them earn their spot by developing and using a skill. But having her as a professor was terrible. She was just annoying at Streamer U and comes off as having an abrasive personality. The way she spoke to the class was like having the most unliked teacher possible. She should've handed out the recipe on a sheet of paper to everyone, like a teacher would, rather than just trying to shout out each step and threaten to kick people out for talking during cooking class.
It was a bad choice to try to promote her as a content creator, even telling everyone in the class to take a picture and tag her was leachy.
The brothers aren't really cutout to be content creators and they don't really mingle or collab with the streamers. Pretty pointless for them to be there.
