I'm guessing that Tyrell hatched that plan after Angela doped Elliot - remember he was anxious about trucks drawing attention bringing in the records. I think Tyrell definitely knew.
As for Angela, she's moving so loose now that I can't say I know. She wanted to know if the building had been evacuated last week....
I have some loopy time travel thoughts about this, but I don't want to go all sci-fi and it looks like Esmail is us with the Back To The Future references.
Also, I know that Tyrell knew about the records, it's the bombing of those buildings that I'm not sure of (who was in the know that knew it was going to happen). White rose, Gyp for sure...not sure about Tyrell/Angela
Feel like a I have to rewatch the last 4 episodes
