Damian was in Gotham. He was the one that saved Tim as he was playing possum after Jason stabbed him.
Tim's history is dodgy because at the time of RIP he would have been 13 and only just joined the family. I follow young Justice and NO nowhere in that title does it say that Tim got his whole history back Mate. Yes he said he had a whole other life but that I took to mean the YJ era which he finally recalled.
Dick was the one who managed Gotham when Bruce was gone.
