Batman And Bruce Wayne Surprisingly Appears Together
4 September 2019 | by Desertman84See all my reviews

"When the Rat's Away, the Mice Will Play" is another episode that has the Dynamic Duo -Batman and Robin - who are facing Riddler once again. In it,we get to see Riddler demands Gotham City to provide him $1 million. Bruce Wayne is handed to provide Riddler the huge amount of money but what happens is that Batman surprisingly appears.

Well,the use of imposters has been usually used in programs such as Mission:Impossible. Evidently,hiding behind masks is obviously an advantage. Nevertheless,it was nice to see how this two-part episode ended.
