Of course, the hazy feel-good hue of Felicity potentially getting the use of her legs back couldnt last all that long, with the episodes closing moments again reverting the action back to Damien Darhk. What we dont know is how he got hold of him, but Damien reveals a new friend for his daughter to play with: William, the secret son of Oliver Queen. Did Darhk snatch William from mother Samantha? Did Darhk kill Samantha? Or has Samantha decided to loan out her kid so that she can party hard in Vegas after finally cashing in that $1 million cheque? We can only speculate for now, but this was a shocking WTF end to another stellar Arrow outing. Agree with these WTF moments or have some of your own? Take to the comments section to let us know.
