Context: Bettel received a very ominous superchat at one point that just had a specific date and time in it, and he joked that it must have come from a time traveller who knew Bettel's exact time of death. When the day came, he capped off the joke with a phony farewell stream... which happened to coincide with IRyS's 3D showcase.
This was drawn in response to a tweet that referred to these two simultaneous streams as a Barbenheimer moment for Cover Corp.
