The research transport that erases the evidence, mends the wounded, and parts from Murderbot as a friend.
ART docks Tlacey's shuttle inside an empty lab module, then orchestrates the cleanup: its drones scrub away all trace of Murderbot and Tapan, it wipes the shuttle's bot pilot, forges feed signatures to satisfy Port Authority, and launches the vessel of unconscious enemies back to RaviHyral so no one will know what happened until they wake. Its MedSystem saves Tapan and heals Murderbot, and it provides fresh clothes from its recycler. Watching Murderbot spare and free the ComfortUnit, ART admits it thought Murderbot might destroy it.
At their parting it refuses to let Murderbot clean and return their comm interface, telling it to keep it in case they come within range again, and leaves it with the words 'Be careful. Find your crew.' What began as menace has become one of the deepest bonds either has known.
Bodiless; a diffuse feed presence in a modular research transport with drones and a full medical suite, disengaging from the transit ring.
Murderbot's staunchest ally and truest friend; the mind that cleans up the aftermath and sends it off changed.
