Other than that, i'm assuming it came down the gangway. Any thoughts? I'm glad that i had a monitor for sure! I'm also glad that i wasn't sitting down there in my new to me boat...

I'm thinking you mean the companionway, and that is the most likely path.
Do you have a vinyl enclosure?
The CO probably came back in through your cockpit and up to the cabin. This is the "station wagon effect" where moving through the air creates a "vacuum" behind you into which your exhaust is sucked.
Think about this; that CO had to go past the bridge deck to get into the companionway. Always have something open forward to keep plenty of air flowing freely front to back, especially if you have the aft vinyl open, or don't have any enclosure aft.
