And that's why Shepard is so eager to do all the stupid things he does in ME2. Still leaves us with two more questions: a) What made him do it during ME1 & 3; b) What about femShep?
Gee, I love Miranda, she's totally worth playing it all over as a male character and cheating on Ashley (especially after knowing WHAT did they do to her in ME3).
Don't need them to be Cerberus. Thane wanted to make the galaxy a better place and Garrus... is Garrus. If he can clean up Omega of Mercs, I'm sure cleaning the galaxy of Reaper-controlled collectors would not be outside his expertise.
I meant, the genuinely stupid things like boarding the 'disabled' Collectors' vessel, making all squad leave the 'Normandy', etc I'm pretty sure, Thane and Garrus are smarter than that especially Garrus with his tactics skills could come up with better ideas
