-The blackout between the flashbang and the escape- We know that Daniel had help editing this video, and it was almost certainly help from either Brother or Tachyon. We know that both of those people like to add dramatic effects to their work. Therefore, it seems reasonable to assume that the blackout is meant to both indicate passage of time and satisfy Brother/Tachyon's creative urges...and nothing more.
-The echo chamber effect- There are two parts to this. First, I reiterate that when we see Lucy running up the stairs, we hear the echoes of other footsteps behind her. I know we have all been in the stairwells of tall buildings and can relate to this noise. Jonas may have only had to deal with Lucy at first, but I think the rest of the Order was not far behind her.
Second, has anyone thought of the effect of firing a gun inside one of those stairways? The echoes would be unbelievable. Even if Lucy were packing, I'm sure that she'd look for other options before bursting her eardrums with a gunshot (and the point about Uma Thurman is well made, and well taken).
-Assumptions about Bree's intelligence- I'm not assuming Bree did anything or thought of anything I didn't see her do or hear her think. This includes putting in earplugs, meditating to reduce the effects of the flashbang, disapparating, or anything else.
-Symbolic flying things-itsreallyreal, I completely agree that Brother flying a chopper and Tachyon's arrival on a plane puts all the flying objects we've seen into a whole new perspective. I'm glad someone else was thinking that.

-Malaysian Air- Bethy, I know there was discussion about Tachyon's plane being from Malaysian Air, but as I recall that was disproved somewhere earlier in the thread. I can't find it right now, but I think it was somewhere in the first 4-5 pages.
-Etc.- Two more things: I agree with the arguments for Tachyon having been in the area for awhile, helping to plan this shindig, but I think it raises a question: if Tachyon was there, did Brother know? Or were his increasingly emo voicemails a cover to mislead OpA? Also, building have fire escapes. They are required to by law. And as some clever person pointed out above, those fire escapes, when in the internal structure of the building, are often right by the elevator.
Edit: one more, sorry. Come and get it: nope, they probably wouldn't say that, because they aren't Cassie. They would say "Tag, you're it," though.
