I think it was pretty much out the window when they arrived in 1974 and 1) Wilfred and Nathan Malik were still alive and 2) the Chronicoms had accelerated S.H.I.E.L.D. technology more than a decade, maybe two. At this point, shit has gone full multiverse.
I don't think it was literal. The Chronicoms are able to change their faces, eye color, hair, and variations of lighter skin tones. I don't know why there would be a melanin matching limit on their adaptability. And they seem to jack the one agent sent to fix the computers well enough.
Why did my heart ache then melt when Deke told Enoch he was part of their family? This constant drumbeat of horror that is 2020 has got me on the ropes with the feels.
In a similar vein, I am 100% on the Sousa/Quake ship. I was sorta about Dansy last week. But Sousa talking to Daisy about paying forward what his combat mate did for him absolutely sold me. Granted, Enver Gjokaj can pretty much get me to fall for any paring he puts 2 sentences of effort into. Cannot blame that on 2020 Trauma-induced Emotionality.
