[Zevran hadn't actually heard Vietnam's announcement earlier; he's been busy. Either his own announcement yesterday was actually far more subtle than he realized, or everyone who wanted to vent their rage spent it in Hughes' act of defiance - whatever the case, no one really showed up to help him or offer any vodka to his cause. This didn't particularly daunt him, and he's simply spent his time since gathering crates of vodka on his own. Scavenging what was left over from Hughes' effort, stealing from homes that have been left unattended, bargaining with those who have access...he's come up with a fairly decent number. Not quite twenty, but close - a little under his intended benchmark, but it's going to have to do.
He's stacked all but one in various places around the building in an innocently industrious sort of way - keeping well away from the door, and anyone who might issue from it. There's been no mention of or repercussions from his announcement, so he's hoping either his false sentiments were approved of, or the men in charge simply have far more pressing things to worry about than what he's up to. He's moved some distance away with the crate of vodka he's kept to himself and is busy fashioning them into molotov cocktails when he hears the first of the explosions and glances in the direction of the factory in surprise. He has no idea what it is - though he certainly has a few guesses - but after a moment, his face breaks into a wry grin.
Talk about luck! Who could ask for a better distraction than that?
He forces himself to wait another ten minutes or so, giving time for whatever forces that might be deployed to the disturbance to make their way there and well away from him. Then he makes his way to within throwing distance of the party leader's home, open create under his arm, before carefully lighting a few of his cocktails and taking aim. And he's always had good aim.
The first bottle actually hits the door, which he would vastly prefer no one emerge from to stop him - at least not yet. After that, he targets the stacked crates; then he tosses one or two on the roof. Liechtenstein's comments about only leaving burn marks have made him extra determined to make sure he does a bit more damage than that, if it's actually possible to...]
[tl;dr - Zevran is currently lighting the party leader's home on fire, with somewhat more planning and preparation than Hughes' attempt. Anyone who approaches will either find him attempting to pitch the molotov cocktails he's got left through windows(in which case they're free to help, if so inclined), or will find him standing at a distance to study his handiwork. Keep in mind that if you want to find him after he's finished, you probably only have a very short window before some form of retribution hits.]
