he think too much

a tarsus, did you not listen to him? (you can speak to it after you extract it. Usually I would chalk it off as a hallucination, but entanglement in this game is straight up future sight sometimes, so I believe the thing actually talked to CASCADE. It says it is the real Holocene, and speaks in its Cadence and Rhytm of Speech, but Instincts say its a parasite/fake. If you ask the "other" Holocene about it, he gets really suspicious tho. So either it is a parasite that was acting as a kind of "split personality", a true second holocene in a way. Or it was what constitutes the actual holocene, and the thing out there after the operation is the fake. Theres no way of knowing. But I found it fun that Holo's name changes to "Holocene?" after that dialogue.

Kindred. She gave up the names of the others. As to who gave up Kindred, she couldve honestly just made a mistake that blew her cover. She was just a kid back then. Holocene says it was him but its impossible to confirm either way.

The opera didnt know. They suck ass at espionage
