Sasuke gives himself twelve hours to just not have to exist coherently, then...
Okay he still doesn't want to be around other people.
But he can send emails.
Tobirama and Minato get requests for written reports on what they thought of Orochimaru and Kabuto and Orochimaru's promises. He designates a snake to watch for messages from either Orochimaru or the other snakes. (There's four distinct factions among the snakes, because of course there are - the three summoners' loyalists, and the neutrals.)
On reflection, he sends a message to the faction belonging to the third summoner, Anko, with an update meant for the Leaf. Here, have carefully curated information on Orochimaru's bases and movements and his promise to cut the human experiments the fuck out. Sasuke could use help monitoring him. (He doesn't need help monitoring him, but this is a good ball to set in motion, and an alliance with Anko's snake faction will come in handy if Orochimaru turns on them again.)
Sasuke has the majority of the stealthier snakes on his side, which means he's actually decently equipped to spy on Orochimaru.
Cam gets a request for some of Orochimaru's messages. And, while neither Orochimaru nor Kabuto record meetings, Sasuke's aware of one of the upper echelon of experimenters who takes meticulous notes, and a very bold little snake was able to confirm how she organizes those. He'd like the transcripts from the time he spoke to Orochimaru onwards. (They'll be encrypted, obviously, but Sasuke expects to be able to break that code sooner rather than later.)
