This screen grab from the promo for the upcoming Arrow episode 'Suicide Squad', to air on Wednesday March 19th, seems to suggest that Harley Quinn will, in the least, be making a cameo appearance on The CW's Arrow television show!
Harley Quinn has been a member of the Suicide Squad in the past, so it isn't unreasonable to think she might actually have a fleshed out role in Arrow, or that this might be a set-up for a future storyline. And hey, the show does air on a Harley Qwednesday!
Here's hoping for big things for Harley in this week's episode of Arrow! Check out the promo below:
