Mobius: 25 Years Later (Unaltered)
In the unaltered timeline, Mace attended Lara-Su's Unveiling and was surprised to see Knuckles out on the dance floor with her. He also became somewhat embarrased when Julie-Su asked if he was with Demi-Na, who he considered nothing more than a friend. (StH: #132)
Mobius: 25 Years Later (Altered)
Five Years Later...
Five Years after Shadow's defeat, Mace worked with members of the Chaotix. He was sent on a mission to Mazuri with Vector by his brother, and as such, did not know of the events that had unfolded at the celebration of the Five Years of Peace. (SU: #5)
Although this isn't confirmed, it was believed by Julie-Su that Mace had something going on with Demi-Na, but denied it, possibly to hide the truth. It was also implied by their conversation that Mace was something of a romantic, as Julie-Su felt the need to stress that the guests at the party were close friends and married. (StH: #132)
- It is unknown if Demi-Na exists in the alternate timeline or was one of the many erased from it.
