The ellipsis carries everything. Lou is no longer the BB in the pod, the infant Sam carried across America and talked to constantly on every lonely stretch of road. She is Tomorrow now, a child, present in a different way. The reflex of the check-in — how ya doin' kid, the automatic reach for the pod that is no longer there — is the game acknowledging the specific grief of successful change, the loss embedded in getting what you wanted.

Sam talks to the BB that is no longer a BB because the habit of connection persists after the form that gave it shape is gone. It is the same grief that runs through the whole Death Stranding universe — the people and things we carry with us in forms they no longer occupy, the conversations we keep having with the version of someone that no longer exists.
