Well, they all have docks in their backs that allow them to attach to the main DOS unit. I have the same docks, but unfortunately a MORON has taken over the DOS unit. We are trying to deal with this problem.
And in case you were wondering the status of the coredroids, well…
The repairs have yet to be fully completed.
I’m blaming the moron for this.
It’s ridiculous, really.
They should all be dealt with in the redemption line.
((You can pretty much ask any Portal character anything you’d like, even cubes and turrets have a place here. Chell and Rattmann would be human still of course, but messages to them might be intercepted by GLaDOS and/or Wheatley))
