If Langdon were a dog, Beck would think he'd be something like a Doberman. Tall and poised, intimidating and arrogant, but sort of simple, just a little dumb. In the way that even the smartest dogs are a little dumb, thanks to the irrefutable nature of being dogs. Their needs are simple, their expectations pretty stagnant, and they spend too much time barking and licking their own groins to have a clear, unbiased grasp on reality.
Narcissus is 'glad to hear' Beck doesn't have a 'crush' on him, and though it certainly started as a harmless joke, Beck's pretty sure there's a nugget of true relief in there. The arrogance is frankly hilarious, and almost endearing in a fucked up, backwards kind of way, but there are plenty of other reasons Beck has to keep an overtly comfortable distance away from people like Narcissus with any kind of relationship, platonic or otherwise—for instance, Beck has plenty of their own intimacy issues to wrestle with; they hardly need to complicate matters with the train car sized baggage of someone else's.
Still, they follow the suit towards the patio; it's not like they have anything better to do, really, and they did come for him, as it were.... though they better not say as much aloud, given Narcissus' ginormous head will probably hear an innuendo in it.
"I have no such plans, don't you worry. I'm telling you, you're a thief as long as I am, the observation thing becomes a habit. Fly on the wall is sort of just how I see the world, now." They shrug.
As they follow Narcissus out the doors, the cool evening air is a refreshing reprieve from the stuffy atmosphere of the 'party'. Beck inhales deeply and it feels like a tonic. "You know something, no, actually. Things have been kind of dry, as of late. Which you'd think in our, er, industry, might be a good thing, like no news is good news, et cetera. But what can I say, I'm easily bored." Another shrug.
The truth is, the busier they keep with high stakes tasks for the gang, the less time they have to think about the hound-shaped demons yapping at their heels, and the better they sleep at night. As it stands lately, they spend much of their days committing habitual, petty theft, and several hours into the night and early morning, doing self-administered safe-cracking time trials, until their tremors become too debilitating to continue and they grow tired enough to sleep through the cacophony of voices in their head.
