Just an FYI for conserving any future ammo. When you upgrade a weapons ammo capacity it gives you full ammo for that weapon. So if you can, try not to reload weapons like shotguns or magnum unless you absolutely have to.
Just in case you're wondering Alex. If you choose to help Sidonis it's revealed that he's suffering from survivor's guilt because of his unwilling betrayal. (blue suns captured him and forced him to separate Garrus from the rest of his squad with a false lead, allowing the blue suns to capture and murder Garrus' team) He then apologizes to Garrus and turns himself into C-Sec.
