There were, quite literally, a thousand things he could have done that would have been worse than what he had. Though Nikola had earned Helen's very pointed stare, it was expected and not the worst thing he could have done. Helen might be mildly frustrated, but she is far from outright angry. This is something they can handle.

She does, however, roll her eyes in response as they move forward through the streets. Of course he would prefer to be Holmes. Naturally. She's starting to think that this might not have been the best endeavor if she didn't want to feed his ego.

"Don't let it go to your head," she mutters, glancing around the streets and gently tugging Nikola in the direction of Baker Street.

It's unfortunate that they won't get very far with this, as the holodeck program flickers for a few seconds, causing Helen to stop in her tracks. It... wasn't supposed to do that.

She manages to get out, "What in the world," before the program flickers again and everything freezes. Helen and Nikola can still move about, but nothing else is working and when she calls for the computer to show the exit, nothing happens.

Nothing happens at all. The whole holodeck seems to be broken and, for the moment, the two of them are stuck inside.

"Bloody hell."
