The discrepancy can be accounted by the time it took the Falcon to reach Ahch-To.

Thought about killing Kylo. Just for a moment.

He found out the plan at the same time Finn and Rose did.

Remember the last conversation Poe had with Finn before the team infiltrated the Supremacy.

It seemed simpler than that.

He didn’t need to know the number.

My own personal rationalization is that the Holdo Maneuver only worked this time because the Supremacy was large enough to generate a gravitational field powerful enough to keep the Raddus from going all the way into hyperspace, thus resulting in the tear in space-time that severed half the Supremacy and destroyed all…

And some random ass no-name First Order pilot in a small fighter takes him out and the the only mention of it is a one liner like ‘yup, Ackbar is dead.’

Your Doylist objections not withstanding, it was Raddus who commanded the Rebel forces at Scarif.

He got the 1st Death Star plans off of Scariff by doing what was right despite the council’s wishes.

Yeah, but that one episode of Rebels showed us that those other ships carry cargo by attaching magnetized cargo containers to the outside of the hull:

Her father is Jewish but her mother’s father was half Filipino half African American, according to Wikipedia.

The Hollywood Reporter article linked above specifically states:

They don’t even have a cast yet and they’re shooting two season back to back. And 2018 is practically around the corner.

Someone didn’t watch the last episode. ;D

You’re underselling it.

Because in this particular case Kara was away from her Earth and her regular support network.
