“What is it?” Henry asks, for all of them.
Does there need to be a comma after "asks"?
The fuller text is:
The fact that Candice has been murdered—it means that there is definitely a killer here, in the hotel [...] “We should search the hotel,” David suggests [...] David says again, “I suggest we search the entire hotel, including our own rooms—unless there is anyone here who objects?” [...]
Henry doesn’t know which is worse—the possibility that one of the people in their little group might be a murderer, or the possibility that there is someone they’re not aware of, moving about the hotel, who has already killed two people. As they search Gwen and Riley’s room, Henry wonders what it is they’re even looking for. He’s not sure why David suggested they search the guests’ rooms, too, not just the empty ones, or why they all agreed to it. He doesn’t know what David expects to find. It feels like they’re playing at something, some sort of parlor game, or murder mystery evening, with the lights out. Only no one’s having fun.
Beverly finds some medication in Riley’s bag and holds it up to the light. “What is it?” Henry asks, for all of them. David looks at it. “For anxiety,” he says, and Beverly puts it back in Riley’s overnight bag.
