'Arrow': Deathstroke Makes His Much-Anticipated Debut In The Latest Flashback (VIDEO)

In an episode that saw Oliver Queen facing criminal charges for being the vigilante called "Arrow," the flashback sequences to the island introduced another fan-favorite DC Comics character. Ollie admitted that he'd been tortured while on the island, and the flashbacks revealed that it was at the hands of none other than Deathstroke.

Thanks to Ollie recruiting his bodyguard Diggle into his crusade, he was able to get those charges dropped. While he was under house arrest and throwing a huge party, Diggle donned the hood to take on some gun smugglers across town. Enough witnesses placed Arrow at that scene to free Oliver of suspicion.

Except for Detective Lance, who will probably never stop suspecting that Oliver is the vigilante terrorizing the criminals of Starling City.

As for Deathstroke, Oliver managed to escape -- with a little help from his mysterious island friend -- but it seems inevitable their paths will cross again. Maybe Deathstroke will visit Oliver in Arrow's home turf.

Keep up with the abs and the action on "Arrow" on Wednesdays at 8 p.m. ET on The CW.
