Pate is looking up? It would seem he'd already know about Church, and Alice and Senda, being like that, and violence and speed, given that he knows-knew Church outclassed them and things like doesn't-didn't sleep. And really, all three were moving around in space with no air source or heat/cold protection. He's not too surprised about Sedna and Church either. So why be surprised about Alice? But Laridia not being concerned is almost like how Pate isn't scared apparently, how neither is particularly upset about Church or Sedna. Maybe it's Alice's reaction, or Laridia's, or something new has shown up. It's rather perplexing all in all at this point who or why Pate is asking about what. Alice not caring is not that much different than Church doing what he did-does. OTOH maybe Pate is simply perplexed Alice doesn't appear happy about Church or sad about Sedna or relieved about the situation or angry at Pate or surprised about Laridia. Like she's given up, or never cared.
All three can move fast in some alternate reality sort of physics way, not that Alice has been all that clear, perhaps she lacks some of it. Where Church simply outclasses the other two combined, usually, in speed (or an added ability to also kind of teleport like that no sleep thing) and in strength, when he's paying attention at least. Still nothing says that Senda isn't faster, but doesn't have that teleport thing going on too. Maybe too weak to be of much use normally, without both the element of surprise and a weapon to fight fire with fire. Past if not present tense.
As to our ancient human-likes. They're not human with these changes and additions they have are they, almost a new life form based upon humans, but obviously not entirely natural or purely organic. Not with these powers to do decidedly non-human things, like moving in warp or ripping off and tearing apart your own arm or not sleeping, whatever each has or is able to get. Overall they are adjusted by DNA manipulation, breeding, cloning; genetic bespoking, whatever. During each individual's "construction" also apparently cybernetic augmentation, nanobot cells, bionics. Super-strong, nigh-invincible, extremely long-lived/effectively immortal, self-regenerating, not requiring oxygen or suitable temperatures. Something that lives 250,000 years (or what have you), is genetically tailor-made to destroy, self-repairing supersteelish instead of bones, and with artificial fiber muscles, can survive at least near-orbit space..... Humaniform somethings.
