Fans weren't sure if 'Fuller House' would be the same in Michelle Tanner's absence. But despite plenty of rumors about Mary-Kate and Ashley Olsen reprising their shared role, the twins never made it onto a single episode of the new show.

And there's no denying that over the years. It would be hard to swap Mary-Kate and Ashley now that they're no longer tots who look almost exactly alike.

Still, the cast's dynamic has remained the same.
