But besides seeing our heroes try to bash each other to pieces for fun, Tuesday and Wednesday's crossover episodes will also be major learning experiences for both characters "It's a great journey for Team Flash because they're forced to address the reality of what they're doing," Danielle Panabaker told during a recent visit to the set of The Flash." When we're in S.T.A.R. Labs it's easy to call Barry and make him run and do super-fast things and save people while we're behind the safety of our computer screens.
