I’m at that weird age where every younger person I meet makes me realize how much l've aged, and every older person I meet makes me realize I'm still a baby.
@anomalynova I saw it as her realizing that what the scientist said was true; "This is bigger than all of us."
Her struggling with the realization that she's as good as dead; "That isn't up to me." and the sudden cut to her still self. It felt very much like showing us what happened after.
