For a time Daniel's content to scrawl in his notebook in silence, but eventually it strikes him how that might be a little more silence than is typical for a shower. He glances at the bathroom door, concerned, but feels that calling to ask if everything's okay would be inappropriate somehow. Then again, there're definitely a few things off about Nick that leads Daniel to believe that he really has unintentionally picked up an offworlder.

Finally his willpower can't hold any longer. The apparent silence from the bathroom means that whatever Nick's doing in there, Daniel probably isn't interrupting anything important.

He knocks tentatively.

"Uh. You all right in there?" Okay, wait. He can't just call things like that into a bathroom. "Is the shower broken or something? Wouldn't be surprised, with the state of this place." Marginally better.
