Seeing as if Shepard is dead or assumed to be dead, what are possible story lines that you guys can think of for Mass Effect 2? It doesn't have to be too detailed, just some ideas on how everything may play out.
First of all, we're talking about Shepard here. Shepard ran around on the outside of the Citadel like a crazy person blowing things up. Shepard is the type of person who loves to be on the front lines during any battle. I don't think it's a stretch of the imagination to think of a situation where s/he could have been killed.
