NP. As
@TopTierHealer posted, there's a lot of interconnected threads going on hidden in shards and the like.
Sandra Dorset, the chick you rescue at the first mission after the prologue, gives you a mission to recover a shard from some Scavs later, and it has data she hacked from Night Corp on their mind-fuckery testing, exactly the same sort of thing Peralez was undergoing. There's also a shard during the Nomad endgame that demonstrates Night Corp was building that tunnel quite close to Mikoshi on purpose, so they at least suspected something was there and wanted easy access. And the Path of Glory ending has you get a mission from Mr. Blue Eyes, who is watching you when you talk to Peralez outside on the terrace. He's also aware of your condition at that time (somehow), and then when you meet at Afterlife for the job the offer is to save your life in exchange for successful completion.
Honestly, there's a lot of great stuff there ruined by the ramrodding in of Silverhand and the insistence on making the next GTA. There's a reason a lot of us are (almost certainly unrealistically) optimistic still about CDPR getting their shit together. 1.5 was, despite a lot of the unwanted balance changes, a big step forwards in making an actual game, and I'm surprised they're still supporting it. Give me rainbows, but I'm hoping we get a NMS situation with CP2077.
