Seeing the explosive stashed into the girl, Eric knew what was about to happen. Resheathing his knife, he pulls the girls coat open and grabs the canister before tossing it further into the building. Yelling as he threw the canister.
"Get the ******** DO-!"
The explosion cut him off. He hoped to have it bounce around a corner, possibly having some protection from it. He wasn't so lucky however, it went off mid air with a loud, supersonic "pop" that nearly blew their eardrums. Luckily for the girl, he covered her as much as he could with his torso, since he was wearing a ballistic vest. He wasn't sure why he acted the way he did, he could have left her, she did try to kill him earlier. Maybe it was her age, maybe he felt bad. Regardless, he acted the way he did, and there was a slightly warm sensation in his leg and arm. Shrapnel, he figured, as he went to stand.
((By the way, I believe most, if not all, tear gas canisters only vent gas, not explode, but I RPed as such. Don't mind me, I'm a weapons "nazi". Like a Grammar Nazi, just weird. xd ))
