I am assuming in my second post (It would have been part of my original, but we hadn't talked about risks yet) that Vi doesn't know where the bride was getting ready.  If she does know, she will go there, if she doesn't, she is assuming that the guards are going to the crime scene to cordon it off while the Captain sees to the maid and is going to follow them.  If she is wrong then she'll loop around to the Captain and the rest of the party... but since she is crap at social stuff that isn't shaking her booty, she is going the parkour route.
