Relationship with David Singh
In May 2015, Rob and David went on their honeymoon.
Attending Barry and Iris' wedding
Rob attended Barry and Iris West's wedding as David's plus-one. Suddenly, the ceremony was attacked by Nazis from Earth-X. Rob and David made it to safety, along with the other guests who didn't participate the fight. Afterwards, his memory of the encounter was presumably erased.
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.
