Relationship with David Singh
In May 2015, Rob and David went on their honeymoon.
Attending Barry and Iris' wedding
Rob, along with David, were invited to attend Barry and Iris' wedding. David sat next to Mick Rory, who he surprisingly didn't recognize, despite he once arrested him a long time ago. He asked Mick if he knew him, and Mick shook his hand and introduced himself. When the wedding was attacked by the Nazis from Earth-X, Rob made it to safety along with everyone else who didn't participate the fight.
Rob appears to be fairly health-conscious, since David Singh is constantly mentioning the "improvements" to his diet which Rob has made.
- In an erased timeline, Rob, presumably, along with everyone else in Central City, was killed by Vandal Savage using the Staff of Horus in his efforts to kill Carter Hall and Kendra Saunders. However, due to Barry Allen changing the time continuum, this disaster never occurs.
