Unmasking Tim Drake's Arkham Knight Secret

In batman arkham knight we find out that jason was missing for at least 3 years but the game makes it clear that bruce made tim drake robin in only a few months or more. Eventually, tim uncovered their secret identities. After jason todd's (the second robin) death, tim contacted dick and informed him of batman's requirement to have a robin to keep his. In one of arkham knights earlier scenes, tim drake suits up as robin to take down poison ivy, who has covered gothams botanical gardens in dangerous new plant growths.
