I don't think this is anything more than Canon Taylor, granted she's not acting exactly like she was in Canon, but that's because she's stuck in a brand new world, is a newlywed wife to a national icon/hero, in a society very different from her own, one that also happens to be embroiled in a reignited civil war, and away from everyone she knew and cared about. So yeah Taylor is very much putting on a brave front at the moment, but she's not an unstoppable badass of Escalation. This is very obvious in the last chapter, 6.
I don't think
@Fencer has stated that this is going to be a memetic Taylor rather than one portrayed realistically to her character, others just seem to have assumed that. Or at least I don't remember it being stated, which might not be accurate, but I don't have absolutely perfect memory, just something that apes it fairly well.
