From what I gather, the spirit was hovering over Vanian's, yes. And looks like Steve is having his own look-see in there now.
Not sure what, if anything, we're doing about the bomb. Yuri's against messing with it, but will play along if enough of the team is determined to do it.
As for the data, Yuri just needs some time to decrypt, possibly defuse, and then sift through all the data aquired from Niel's. Then there's the possibility of something being on the commlink Johnny found, too (and some of those programs look kinda juicey).
Vanian's home address is something we'll just have to look into some more. Heading there soon(-ish) would probably be good if we hope to find him alive. Or at least to find those blueprints.
