I'm not totally certain, honestly. She's personal friends with 2 sirens and knows 1 more, all of whom have powers that alter reality in some way that appears to be magic for all intents and purposes, but is sufficiently advanced alien science that affects the women's biology. Not to mention this is over 40k years in the future when you can literally shoot fire/lightning/acid from guns, have energy shields that can absorb enemy bullets to add to your own magazines, hit back at melee enemies, and more, not to mention the entire science behind "digistructing" objects and teleportation stations and of course the eldritch abominations contained in pocket dimensions behind the Vaults... Yeah, she's probably likely to find some manner of scientific explanation for just about anything she sees, or at the very least believe that it has a scientific explanation even if she can't figure it out. :P
