Tommy was killed and revived over and over again by Dream..now ending up emotionless and ivory.Tubbo and Ranboo always try to make him smile..or react..but nothing.. sometimes he manages to show emotions trough actions..tho he has always the same blank expression.he has entire white hair in consequence of his deaths.

you see him near the shore on a beach..just standing there, looking at the sea.. completely emotionless, still with that blank expression.. (art by Bludoby on Pinterest)
