I swear he has killed if Rory like 5 times at least! well if you include the part when he didn't exit, but I suppose that isn't really death so.. yeah, I'm gonna count it as death. I suppose, like, constant death comes with the job!
I do love Rory. He's just so laid back for a companion. He tends to just roll with whatever's happening around him. Or, at the very least, he shrugs it off as part of what goes on around the Doctor and Amy and keeps going.
