Shepard was finished – finished with Cerberus. She should've known the Illusive Man would follow her to Thessia. What she didn't expect was that Kai Leng would get to the better of her and steal the data about the Catalyst they so desperately needed. Without it, the Crucible couldn't be finished and the Reapers would win for sure.
And now Thessia had succumbed to the Reaper invasion. Liara completely understood the pain and despair Shepard went through when Earth was hit. Liara took it hard and broke down in tears once they returned from the mission. Shepard held sympathy for her; she just saw her world go up in flames.
Shepard comforted her friend the best she could. She didn't dare utter 'It's going to be okay' because nothing was okay. All Shepard could do was sit next to Liara and rest a hand on her back.
Even through all the sadness and anger, Shepard wasn't about to give up just yet. She swore to herself she'd track Kai Leng down and she'd get that data back in time to save the galaxy.
