[Looking at Aqua] "Who is this dickhead*?"

"Why does he keep doing that"

"Get him off my screen. "

"Why is he here."

(String of curses I don't know the english translation for, after he used his useless skill while she was in the middle of playing)

[Talking to him] "What is it that you do. What is your purpose, really?"

MANGA SPOILERS

Qifrey said that part of the experiments was to wipe his memories so he could be restored from being a tree. But he also says what he found in the Tower was only a scrap, and though it made him remember some things it was still not a lot, since he also tells Coco that his childhood memories are all but lost.

Now what I'm thinking is that, through those treeifications and restorations, there would need to be at least one person to make him feel safe enough for the tree to sprout, right? What if, their way to make the silverwood retreat was by killing that person, forcing him to grieve over them? That, I think, would make for more important notes on their experiments than simply wiping his memories. It could tell them how much grief is needed for the silverwood to retreat.

So through that, what I'm thinking, is that Olruggio practically saved his own life by wiping his memories. Because if he hadn't, the Brimmed Caps would find him and kill him in Qifrey's presence to force the tree away.
