I was a bit disappointed when they killed off Shrapnel. Not because I found him interesting or anything, because he was kinda lame and showed off that Suicide Squad wasn<t screwing around when it came to killing their operatives but because you had Sean Maher play him. In a tv show where Summer Glau also has a role, im not saying they were obligated to make a Firefly reference but you had Simon and River Tam and it would have been fantastic.
Also we haven't seen Summer Glau's character in like 10 episodes, where is she ? Are they just holding her over for season 3 at this point ?
