'Arrow' Season 3, Episode 14 Spoilers, Plot Rumors: Old Characters Make A Return Appearance

 "Arrow" fans may anticipate the return of more characters from past episodes when the show airs today on The CW.

The hit television show, "Arrow" will be bringing back more characters from previous shows when the 14th episode airs on The CW today, Feb.18.

Last week, Sara Lance, who was earlier killed off in Season 3, made a special appearance. Viewers were also treated to Thea and Oliver traveling back to Lian Yu to start their training in readiness for an anticipated attack by Ra's al Ghul.

This Episode 14, aptly titled "The Return," viewers will be seeing Cynthia Addai-Robinson, who'll play Amanda Waller, Slade Wilson, and the erstwhile Tommy Merlyn. Plot spoilers include Slade's making full use of Thea and Oliver's arrival to escape his underground bunker prison.

Thanks to Malcolm Merlyn, the brother-sister pair end up uncomfortably close to Deathstroke (Manu Bennet), Oliver's old nemesis from the past.

Based on the episode's preview photos on Cinema Blend, Thea's fans can cheer her on as she shows an unrelenting mercilessness unleashing her revenge on her mother's murderer, Slade. In an unexpected turn of events, it is Oliver who will end up holding his sister back.

Tommy Merlyn also makes a surprising return in a flashback when the camera pans over to Oliver and Maseo's (Karl Yune) Starling City mission to take possession the much-touted Omega bio weapon, all under Amanda Waller's (Addai-Robinson) stern warning not to reveal his (Oliver's) identity. But it is Waller who is revealed to have brought the two to Starling City in her hidden agenda to locate China White.

In the middle of all this, Oliver is fortunate enough to send a message to his family, Laurel and Tommy.

Season 3, Episode 14, "The Return" will air today on The CW at 8 p.m. ET.
