I tried today. Nothing happened, didn't find anyone to talk to, couldn't visit Hanna or enter any of the other hiding places, couldn't enter my apartment, nothing.
What I ended up doing was approach Nela from the front instead of from behind. Aaand I got yet another mystery-teleport behind her, then the same cutscene and you know it from there on.
One more argument in favor of the theory that the whole scene was supposed to be a cutscene but someone forgot to flip off the interactivity switch.
And since Zoë was literally blown away...
Even if she wasn't killed, it would take a massive plot hole to explain (or rather, not explain) how she wasn't very badly injured.
As V already pointed out, it's the 23rd century, and wonders of the future technology... To put it simply: A Wizard Did It.
As for the dude grabbing Zoë after the blast, I really have no ideia. Maybe he's after the box Nela gave her? Or maybe he's simply trying to get rid of the body? It might be easier to explain "she vanished" rather than "she was killed during a terrorist attack in which she may or may not have been involved".
The dude is obviously Falk Friedman. Which makes me suspect he or his Fräulein orchestrated the whole bombing to force Zoe's awakening, after which they're gonna snatch her and use her for her plans.
