On my first playthrough of Mass Effect 2 I just completed Jack's loyalty mission and it sparked an arguement between Jack and Miranda. Miranda is no longer loyal. Is there a way to regain that loyalty? Or am I screwed and she's just at normal now.
I **bleep** off Jack and had the same problem, but if you talk to her afterwards a paragon/renegade speech check comes up. If you have a high enough paragon/renegade level you can do some fancy talkin' and gain her loyalty back. This should be parallel for Miranda, aswell.
You're basically screwed. Miranda will probably die. Re-loyalising Jack/Miranda is the hardest Paragade check in the game, and it is fairly probable that you'll never amass enough points to woo her back. Try not to get attached.
