As tiny and inconsequential of a moment that it is, there's one singular line in Severance s2 EP 5 that absolutely shattered my heart,
It's in that scene after Irving's funeral, after Milchick pulled Ms. Huang out before she can perform the Theremin, she protests with a simple "But I practiced!"
It's such a harsh reminder that she, above all else, is still a child. It means that she was proud of her theremin playing, and that she actually looks forward to actually getting to play it for people. She complains to Milchick in that scene like a little girl complaining to her father because she missed a chance to prove herself. It's the most human thing we ever hear Ms. Huang say.
And looking at her, what do we even really know about Ms. Huang? Other than the fact that she's young, and claims that she was a crossing guard before working the severed floor? We know she takes the place of Milchick's previous position, and he's not severed. But we got to see Milchick outside of the building. We never see Ms. Huang up to any activities outside of what goes on in the severed floor. Does she live there? After all, how would Lumon be able to cover up the optics of a child working for them? If a kid was publicly working for them, wouldn't the anti-lumon crowd be vocally condemning them? Wouldn't we see someone on the news with a 'Lumon practices child labor' sign?
And if she does live there, and her life working as assistant manager of the severed floor is all she knows, then does that mean that Milchick really is the closest thing she has to a father? And the Innies she oversees, as detached from them as she is- (hence the "I'm your supervisor, not your friend" line) Close enough to a family that some part of her craves the idea of impressing them?
When did she practice? Does she have any free time to do so? Did she cram extra time on the instrument during meal breaks? Did she learn the theremin completely from scratch down there? If so, did she start practicing by playing kier hymns? Has she tried to compose her own songs?
'But I practiced!' is the most emotion we see Ms Huang express and I think it's absolutely gutwrenching considering the implications.
