Sorry Hydro, not good enough, you got the penalty.
Sammy's asthma will definitely be set off by the fumes, but since you are not currently in them, they are a lingering effect, they will not stack up. She will still get the wooziness penalty for the rough ride, she may like roller coasters, but she is not immune to the effects.
In an incredible stroke of bad luck, both Icarus and Matt glitch their initiative rolls so anyone trying to move out the port side quickly will take a penalty of -2 unless they hold actions or choose not to be cute about things. But since that is probably just Heron, I don't really think he will try it.
p.s. WOO HOO 100 pages of OOC content!
