What if.... Frieza gives bardock a second chance? What would happen? (And btw I'm going to have someone else instead of gine so don't get mad...)

Shepard has had Tali on his team since the start. But after he learns of Tali's feelings towards him, he gets a little off guard. But can she trust him enough to tell him her feelings? But Shepard doesn't want Tali to get sick, because if she takes off her suit the consequences are high. Will Shepard dump Tali for her safety, and break her heart, or will he try to make this work? All while trying to build the team to fight the Reaper's.
