niall really is a little rat, and i mean that in every possible dimension of the word—maura might have named it first, but episode 5 proves her right in real time, even beyond the literal ratting out of ruben and his rodent-like tendency to be so quiet as to sneak up on you without meaning to.
look at how he moves this entire episode! the whole thing is a slow, methodical orchestration—and it begins with ruben venting about mona and the dance class while simultaneously pressing niall about the money he can't repay, and niall already filing both things away together, already sensing that they might be useful to each other. that's the thing about niall: he doesn't move through people directly, he moves through the space between them, entering softly and apologetically, mild-mannered in a way nobody resists because it never announces itself as threat. from that position he catalogues everything—fractures, sensitivities, which bruises exist and exactly how much pressure they can take.
when he finds himself alone with mona the next evening he placates her, draws her out, and then right before he leaves turns back and drops the line about how free she looked while dancing at school, framed as an afterthought. ruben arrives furious the following day and niall performs innocence so convincingly he gets rewarded for it—handed even more access, sent to monitor her at the dance class, told to keep an eye on her drinking because she tends to spill her guts when she has a few. once the class ends, he apologises to mona warmly enough that she lets him take her for a drink, ruben’s instructions repurposed into tools. at the bar he shares that ava is pregnant—a vulnerability placed into circulation so that one can be extracted in return—and walks away knowing ruben is infertile. another pressure point successfully acquired.
after ruben finds out mona told niall and the wreckage is everywhere, niall is right there—i'm so sorry, he forced it out of me, you deserve better, i love ruben but he's lost his mind—always the gentle one, the good one, the comforter, helping mona clean up the destruction he helped engineer before sleeping with her on the floor. and when she's indifferent about it, when she makes clear he was never anything special, that sting gets redirected outward.
he leaves ruben a voicemail telling him there’s something he should know about benji. ruben then shows up asking about it and niall deflects, obfuscates, plays confused—oh no, you've got the wrong end of the stick, it's in your head—until ruben mentions the dressing gown smelling different, and niall goes quiet. after a moment, he says: well, i don't know the extent of it.
niall doesn’t lie outright, but he doesn’t need to. he says only enough to remain plausible, just enough left open for interpretation to take over—letting ruben’s own insecurities and paranoia do the rest. ruben draws his own conclusions and rushes out the door, and that distinction is everything, because niall has made it so he can retain deniability and absolve himself of what follows.
this is what niall has strategized, completely without force, instead relying on proximity, patience, and the precise calibration of what to say and what to withhold—allowing other people’s damage assemble the destruction while he remains elsewhere in posture. crucially, niall doesn’t decide outcomes; what he does is more insidious than that. he produces the conditions in which outcomes feel self-generated. he suggests, he withholds, he says things like they aren’t a big deal, and lets people react themselves into escalation while he stays calm, measured, and impossible to accuse of anything. where ruben destroys openly, niall corrodes from underneath.
