The 100's Jasper Jordan is back in action.

The exuberant teen that fell to Earth at the beginning of season 1 is no more. The last five months on the ground have not been kind to Jasper (Devon Bostick), and season 3 saw the character spiral into a deep PTSD-induced depression. Busy flirting with death, drinking himself into oblivion, and toying with the idea of escaping into Jaha's (Isaiah Washington) promised land, Jasper has hovered in the background for most of the season.

Now that Jasper is embroiled in the ALIE battle, however, he has found a new purpose (Jasper busting out of Arkadia is our everything, by the way).

"There's still a long way for Jasper to go, but I'm excited because I think now that Jasper is part of the ALIE storyline, he's been given something to do," Bostick, 24, told EnStars at WonderCon. "It might distract him from being flooded with emotion."

That's not to say Jasper's PTSD or his anger at Mount Weather will instantly dissipate. Even in the heat of Raven's (Lindsey Morgan) rescue, Bostick's character still had time to throw a verbal jab at the recently returned Clarke (Eliza Taylor).

As for those viewers who think Jasper's dark turn is "annoying," the actor hopes they can learn to sympathize with the youngster's plight.

"I hope people can see he's really just suffering. He's not being annoying; this is a kid who needs help. He needs attention. People need to talk to him and it's just not happening because there are so many things going on in the world. He's just a kid in trouble. Yeah, everyone's going through stuff [but] it's just affecting him differently," Bostick explained. "That's not a reason to criticize him, he should be loved even more. I really feel for Jasper and I'm excited for his progression."

See how Jasper handles a delinquents reunion as Raven slips over to the dark side in "Nevermore" (see a preview below). The 100 airs Thursdays at 9 p.m. ET on The CW.
