Dunno, but would at a minimum start voting for;
[X] 9S
Either to keep an eye on him, or possibly in b4 he either get's strangled in private, or worse a victim of either a Renegade 2B/WTF twist, or worse converted by the "Big Adam/ska".
And to IC keep a check on the apparent results on searching for 2B IC, while maybe giving 9S some overdue passive therapy before he goes "Jack the Ripper" on us.

Also, in before we'd have to maybe interact with the Pods a bit, 'least longer term Big Bro Adam ends up with a few pods on his side, and Mission Control going all "Sons of Liberty" on us again...
... And also, in before we end up with "Eve" as his possible 'child' with 2B at the way things are going, if trying to replicate a 'Snake project' unearthed under 'family'. Which might end up instead going all "Cain & Abel" That could invite a Drakengard! Plot twist.
EDIT: Alternatively, depending on circumstances...
We might want to IC do at some point;
Contact the Commander. (Under disguise.)
If by some chance, we want to privately inform her on if we IC discover a "Renegade" 2B, yet want to speak to her personally instead of 9S, over fears that there's a chance... He might not take the news well, if he learns of that fact.
