Wonder Woman 1984: 5 Ways Steve Trevor Could Return

A Hallucination or manifestation may well be the most plausible way to bring Trevor back into the franchise, but it doesn't have to be the work of an evil bad guy. Diana may simply see him in her head - like a ghost, but not in a creepy haunting sort of way. Perhaps it's Diana's way of dealing with Steve's loss.

He was a big part of her life, after all. He helped her become the hero that she is, and then she was forced to him die in front of her. That's bound to have an effect on her - no matter how powerful she is. Maybe she speaks to him in her head as she's not ready to say goodbye.

Or perhaps she blames herself for his death, and this is why she continues to see him. Or maybe she calls upon him for inspiration when she's dealing with a dilemma. So many possibilities. But regardless of how it happens, a ghostly manifestation of Steve Trevor is looking like the most likely option.
