Cell says that in the future he came from, he killed Trunks and stole his time machine. This Trunks is distinct both from the Future Trunks who came to the present and from that character's death during the Cell Games.

The deaths of Androids 17 and 18 are unconfirmed in Cell's alternate future
Cell says that Androids 17 and 18 were no longer present in his future and speculates that Trunks may have defeated them. The use of a shutdown device also remains hypothetical. Their absence is not converted into confirmed deaths, and this timeline is not merged with the other future in which Trunks returns and kills them.
