Stephen Amell Poses With Deathstroke While Arrow Shoots Its 100th Episode

Could Deathstroke reappear in the one hundredth episode of Arrow?

We've already heard that Jamey Sheridan (Robert Queen) and Katie Cassidy (Laurel Lance) will make guest appearances in the episode, which is set to be the third part of this year's four-way super-crossover between Supergirl, The Flash, Arrow, and DC's Legends of Tomorrow.

Now, series star Stephen Amell has tweeted out an image of himself sitting on a park bench, looking very cross with the man on the other end -- Deathstroke.

Manu Bennett appeared throughout the show's first season as Slade Wilson before stepping into the role as season two's big bad in the Deathstroke costume. He would appear in one more episode, in season three, but has voiced his discontent with how his character was handled.

With the show's hundredth episode being what executive producer Marc Guggenheim called "a love letter to the show," could fans see their favorite villain once again in the form of either a current-day Deathstroke, or the season two version by the magic of time travel?

It doesn't seem entirely impossible -- although with the recent revelation that Deathstroke will be the villain in Ben Affleck's Batman movie and possibly even show up in Justice League, it's hard to imagine that his Arrow appearance will be much . Warner Bros. has shown a tendency to remove characters from most of their TV properties if those characters are going ot go on to play a bigger role in the movies.

Quizzed on exactly that on his Facebook post (see above), Amell commented that the photo was taken today (September 26, 2016), which seemingly suggested that as of today he believes they're able to use the character of Deathstroke on Arrow, although he doesn't say outright that there's no truth to the rumors that characters become "off the table" once their movies are on the way.

Deadshot, Amanda Waller, and Katana -- members of the Suicide Squad cast -- all apeared in their Arrow form after Suicide Squad was already in production, and Affleck's Batman isn't in production yet.

Another question might be whether we could see Amell wearing the Deathstroke armor for some reason, since the image above shows an armor which seems (from the lack of visibility inside the eye) like it could be empty.

Arrow airs Wednesday nights at 8 p.m. ET/PT. New episodes return on Wednesday, October 5, on The CW.
