In fact, Coconut was not the only one in the party who vomited. The maintenance guy and Mouse had vomited twice, but their condition wasn't as severe as Coconut.
The wound on her hand, which had been bandaged by the Doctor, seemed to be unable to heal. Fresh blood kept oozing out, and she needed to change the bandage every once in a while. Even under the effect of the tranquilizer, Coconut did not seem to be feeling very well. Her lips also seemed to be on the verge of cracking.
All that and not to mention the lingering nausea: the players could basically feel it, but the degree of severity was different. There was also a faint sour smell in the air, but it was not that obvious.
The players had already left the bookstore and got back into the jeep.
