Well that's not good! Rider picks up on scents quickly and be quite alarmed as she gets the smell of blood from the smoke (blame her bloodlust for that)- she'll suggest they leave immediately whilst asking Xingchen to check on Albedo in case he's injured. She's ready to help them get out if anything goes wrong.

Xingchen'll get the scent of mountain flowers- and might take a nice deep breath of it before realising the danger. He'll dizzily try and help Albedo as per Rider's request, who doesn't actually need healing, and then help look for the way forward out the room.

Albedo's also pro-leaving the room (if a bit confused why she's asking if he's hurt, and will remark the smell "reminds him of a sweet from home").
