The CW's superhero series "The Flash" already released the official synopsis and spoilers for its upcoming twelfth episode for season 3 titled "Untouchable."

The synopsis reads, "Barry (Grant Gustin) and the team at S.T.A.R. Labs work together to bring down Clive Yorkin (guest star Matthew Kevin Anderson), a criminal meta-human who is methodically killing people by causing them to decompose at an accelerated rate. Joe (Jesse L. Martin) becomes his next target but it's Iris (Candice Patton) who is caught in the crossfire. The Flash mentors Kid Flash (Keiynan Lonsdale) and begins to elevate the newer speedster's training to another level."

In addition, The CW released official teaser photos showing Barry training Kid Flash in their effort to defeat Clive Yorkin, by doing what they do best. As pointed out by the synopsis, Barry hopes Kid Flash will become fast enough by the time they face the enemy.

In other news, it is speculated that someone is going to die in the upcoming episode of "The Flash." To backtrack a little, Barry was already warned by Savitar (voiced by Tobin Bell) during the mid-season finale that dark times are ahead.

As Barry already travelled to the future, he saw that Savitar will murder his lady love, Iris. Even though there is speculation that somebody will die in the upcoming episode, many suspect that it is not Iris just yet, as it is already confirmed that the character will still be alive by the end of season 3.

Speculations, however, point to either Julian Albert (Tom Felton), Joe, or H.R. Wells (Tom Cavanagh) as the unfortunate soul who might die next.

Julian's alter-ego, Dr. Alchemy, is currently serving Savitar and it is possible that he might sacrifice himself to get rid of the evil. It may also be noted that actor Tom Felton is only credited as a special guest, so it is an indication that he might not be present before or after the third season ends.

Joe, meanwhile, is also a possible candidate because he might end up sacrificing himself for Iris' life. H.R. Wells is also a candidate because he was seen on the same rooftop where Iris met her death, so it may be possible that he will suffer a similar fate.

To know for sure, catch new episodes of "The Flash" every Tuesday, at 8 p.m. EST on The CW.
