Behold! The Flash/Arrow crossover trailer. Looks like Oliver Queen (Stephen Amell) is a bit of a bad influence on Barry Allen (Grant Gustin).
This will be the eighth episode (imaginatively titled, Flash vs. Arrow). Episode 5 just aired in the UK last night. So, that means… carry the one… Ummmm… I’ll let you do the sums as to when we can expect to see Barry and Ollie team up.
