I can't buy for one second Jenn was shrewd enough to randomly interject while Tim was talking about something totally unrelated (new tripod) as she joined back in the convo, and used that moment to pretend she edited a vlog that day to try to prove this new person from Tattle wrong about when renovations began. She didn't know the power wasn't off, she didn't know how to make instant rice, she didn't know what the line from the pool cage was, and everyone here thinks she has no clue what is going on ever - but she came up with some sneaky plan to randomly mention Legoland editing to prove some fake renovation tineline?
It's possible the guys started weeks ago, then paused, and started more things recently?
