Identifying yourself as a nobleman to the Levellers? I think you're thinking with your hammer.
Larric slumps a bit as the fire dies out- thinking about it, trying to make sure it stayed
put out was probably what took the extra time and effort, since a fire once snuffed may reignite if you don't keep it snuffed. He turns to scan the room, as if to police up his goods and make a run for it out of town, but they're in another building, since he just happened to be in this house because of diving for cover by coincidence.
So he drops the reflexive action of looking around for them, and heads toward the windows in the front, crouched over to avoid drawing unnecessary attention, so as take a peek outside and see if he needs to run or not.
He arrives just in time to see the knight in shining armor raise his shield and block a crossbow bolt, then look in Larric's general direction before returning to the fight. Larric looks about, seeing a large fellow of somewhat dubious character (William) holding a freshly loosed crossbow. The words "dibs on his armor" drift through the alchemist's mind... Two plus two equals folly, at least in Larric's frame of reference.
He shouts at the crossbowman: "Are you out of your mind?
Come on, let's get out of here before he sends a squad after us! Out the back way!" This is loud enough that others in the house are fairly likely to hear it. Larric turns and trots out the back (diving through window if necessary), glancing over his shoulder to see if the crossbowman decides to leg it.
Larric's first thought is to get to his luggage before anyone burns it or takes it away, and that's the direction he heads; I assume the luggage would be at whatever lodgings he'd had for the night before. Given that he's traveling with at least fragments of alchemical gear and some books, he might have a pack mule or the like as well- DM discretion there.
Also at DM discretion, and I imagine he would deem this convenient, he may coincidentally be headed in the same direction as the vegetable garden full of rebels that Alfred the hammerer just stumbled on...
