Do you think Tibbs and Gillespie will keep in touch?
Or are they done forever?
On one hand, the last scene hints at a final farewell (“You take care now”)
On the other hand, there was a clear friendship that developed between them, which is big considering Gillespie’s prior racism. Gillespie symbolically carries Tibbs suitcase. Tibbs smiles when he gets on the train. Etc
Do you suppose they would call, write, maybe visit occasionally?
