I know right, the cut off at 45 minutes caught me off guard. After revisiting the episode... I think many of us have been missing what actually happened here. Heres what you may have missed:
By demanding access to the computer from the guy with the Bernie sticker on his monitor, Elliot figured out that in order to save the data before hack 2.0 goes live, he needed to get to the floor with the saferoom that Angela was supposed to tell him about, but didn't. Elliot knew he'd need to get the financial data onto an external hard-drive, because its going to be destroyed by hack 2.0 and all the physical info will be blown up too. At this point those outcomes are a forgone forgone conclusion to Elliot, then he gets forced out of the building, and immediately calls the building facing explosion and warns them about the bomb, then deals with Darlene.
Then he snuck back in after the protestors got through security, off camera, and goes up to that room, BUT doesn't arrive there until after Angela (stay tuned).
Why would Whiterose give ELLIOT this job? Whiterose knows about Elliot's split personality, so does Irving, and they wouldn't be naive enough to have Elliot (who's clearly in Elliot mode, hence the weekend sleepover with Angela and Tyrell) try to further stage 2. The directions clearly involved storing the financial data, about to be lost to the hack plus bomb on paper copy building, onto an external hard drive, something that he would have been down to do because that could be used to undo the damage.
Angela fukked up when she didnt answer Elliot's call. He already knew what needed to be done, and managed to get back in the building after the protestors broke in. She could have told him she had a way to reverse and he would been like, im already on that. Why did she do that? She didn't want Elliot to know she was subverting him via mr Robot and was in bed with the Dark Army. So she did it herself.
Right after she exits the safe-room and escapes wearing the fSociety gear, as she gets into the elevator, you can see a man with a backpack and a hoodie with the hood up, sprinting through the back of the shot in the direction of the safe-room, which Angela just came from. Thats Elliot, going to do what shes already done! He gets in there and finds that its already been done, and determines it must have been Angela, so he goes back down to her floor and intercepts her after she meets with sandwich man.
As we've seen in previous episodes, Sandwich Man is used by Whiterose to fix situations. Elliot was supposed to be compromised and killed, but it was Angela instead because she didn't follow directions--and now she is compromised.
Elliot's going to realize she did it because she thought everything could be undone, and they're going to escape, but the Sandwich man has the data after Angela gave it to him in exchange for a bag with a gun in it.
The plan was for Elliot to die, now Angela has done what he was supposed to. Or has Elliot undone what she did?? Hmm. I had the impression that the hard drive had the data needed for Whiterose to "fix" everything, thats why Angela is on board in he first place.
What do you think? I think I'm hot on the trail!
is she on par with Elliot's skills?
when Angela screamed "Over here!" and the security guards last memories were splattered all over the floor by DA goons. Them DA boyz do not play 
They couldn't wait to cause chaos and mayhem. But I believe that is Elliot running towards the safe room to undo whatever they had planned. Its just mind fukk after mind fukk...
