Yes. When he outed you to Hale for punching Han he left a note asking Hale to upload something onto his computer. I eventually rolled back Hale's computer for him, but the damage was already done to the network. But, to be honest...I don't understand why if he knew about the backups that he would only try to mess with Han's? I assume he was exploiting the admin network to be able to get through to Vivienne's code, but why stop there?

[ literally it makes no sense to him ]

He would have forgotten what he and I had together.
