Yeah, but when your cover is "What? I've just been hanging out here on my way to Alderaan", it's a bad lie.We can write off Leia's feeble excuses as last-ditch efforts, but they sound really dumb in context, lol.
To me they always came off as someone lying through their teeth... I mean even as far back as '78. She got caught red handed, she knew it, he knew it. It's like when a cop pulls you over and you say you were doing 55, when you were really doing 70.
When your cover is "What? No, I swear that wasn't us blasting away from the battle of Scarif as you tried to mow us down with a lightsaber", it's a different level of feeble. Not to mention Darth Vader doesn't call her on it. And, again, we come back to the fact that the plans weren't beamed. And he didn't trace any Rebel spies to her. And his buddy seemed to have no idea that he had just been at the battle of Scarif chasing this specific ship.
I mean, the guys on the Death Star had heard about the Millenium Falcon and knew the ship matched its description of the one blasting its way out of Mos Eisley. Now they can't identify the Tantive IV?
This be prequel-excuses territory, mateys. Next let's talk about how Anakin Skywalker invented C3PO but never recognized him, and how that was totally cool.
It's okay guys. We can admit Rogue One has flaws. They won't take away your Star Wars license, lol.
The 'rebel spies' trail:
Erso
Rook
Saw
Jyn
Generic rebels on flag ship
Generic rebels on Tantive IV
Leia (only one not dead after other rebels are killed or executed after capture)
Sounds like she really was the last link the imps were looking for to lead hem to the plans and the secret base.
