Arrow Season 2, Episode 10 aka Arrow 2x10 ("Blast Radius") airs on The CW on Jan. 15. The quest for justice is about to get even worse for Oliver Queen (Stephen Amell). Roy Harper (Colton Haynes) may have been changed forever. The two DC Comics heroes are expected to make the 2014 premiere episode quite explosive.

Spoiler alert: This feature contains spoilers on Arrow Season 2. Episode 10, Blast Radius, is the first 2014 episode of this DC Comics adaptation.

Suspense filled the show's avid viewers during the mid-season finale, "Three Ghosts." A lot of things have been set in motion in 2013. Roy Harper, now fortified with "The Miracle" serum, could become Oliver Queen's official sidekick. That is, of course, if he doesn't lose control.

Slade Wilson aka Deathstroke (Manu Bennett) has gone from Oliver Queen's BFF to worst nightmare. Oliver himself injected him with the Mirakuru or The Miracle serum to save his life. But Slade couldn't forgive him for not saving Shado (Celina Jade). This was revealed in Arrow 2x09.

Spoilers reveal it will be Deathstroke vs Oliver Queen in the second half of Arrow Season 2. But first, Deathstroke will be attacking every character who matters to the green hooded hero. Who will come to help -- Roy Harper, Black Canary?

It is not shown how Oliver took care of Roy Harper after he got the Mirakuru serum in Arrow Season 2, Episode 9. (Barry Allen (Grant Gustin) used "rat poison" to detox Oliver.) Ollie wants his trusted people to look after Roy, without specific instructions. Is The Arrow hoping the serum has made Roy Harper stronger so he could be an official part of his team?

The Black Canary (Caity Lotz) is still appearing in Oliver's island jungle flashbacks up to Arrow Season 2, Episode 9. It is believed she will return to the Starling City in costume if Oliver and her sister Laurel Lance (Katie Cassidy) wind up in grave danger.

The question/speculation remains: Will the original Black Canary die in Arrow Season 2? If so, how long before Katie Cassidy becomes the new Black Canary?

So much is going on in Arrow Season 2. Olicity shippers couldn't complain when it comes to moments between Ollie and Felicity Smoak (Emily Bett Rickards). But the next focus will be on Roy Harper, as viewers want to know how his body reacts to the Mirakuru serum. Will he become a foe before he becomes an enemy? Fans don't doubt Oliver Queen will manage the situation any way.

No sufficient spoilers are available on Malcolm Merlyn (John Barrowman), or whether he'd be in Arrow Season 2, Episode 10. What has been revealed so far is that he's the biological father of Thea Queen (Willa Holland). But Moira Queen (Susanna Thompson) now has a leverage against him. Apparently, the Queen matriarch's reach extends up to the League of Assassins.
