Wait. If c!Tubbo never told Ranboo about the festival, and neither Wilbur NOR Techno has told Phil about Tubbo's execution...
Phil nor Ranboo knows why Tubbo is really scared of Technoblade. All they think is that Tubbo is afraid of Techno because Techno's an anarchist.
NEITHER OF THEM KNOWS.
If c!Phil finds out, what would he even do?
Canonically, Phil found Tubbo in the box and sees Tubbo as his second (slightly lesser important) son. c!Phil is closer to Tubbo than to Tommy...
I can't believe Phil didn't know
