It would not be the first time Bee and Theo, have fallen out with people. The builders who built the roof and veranda, quit before they completed the job. They made a video about it, from their own perspective obviously!
I did wonder why Nick didn't appear in anymore of their videos. Instead they enlisted the help of someone called Ricky, who mysteriously started appearing in the videos, with no real explanation, until much later. Ricky has his own channel now - Life by Ricky. Unfortunately he is somewhat tainted by association now!
