We all know how Damian tends to use the people he considers friends (or allies). But once, he did this to Tim.
He needed someone with Tim’s strengths and needed that dedicated to the mission full time. So he “gifted” Tim with some Turkish coffee shortly after the man actually had a full night’s rest while he pitched the parameters of the case.
The result? Tim stayed awake for nearly two weeks straight and solved Damian’s case, as well as five other cold cases in the batcomputer’s files before Alfred flushed the remaining coffee and Dick injected Tim with a sedative to knock him out.
Damian’s “requests” for help now have to be submitted via email, where Bruce can view them for approval.
