Rae's desperate search for her mother was probably consuming too much of her attention at the moment. Between that and making sure all her friends got out of there safely, it was a miracle that she had any of her wits about her to stay alive herself. She knew, though, that they might not survive if she didn't help them out. And she was trying, desperately trying, to stay positive, but her mother was usually the one there with reassuring words, promising her that everything would be okay.
Shaking herself out of her obsessive stupor, she helped Miriam, Aaron and Eli start heading toward the buses. She'd fight people out of the way to get them on one if she had to.
Eli shouted for her and she gently grabbed the hand that wasn't being vice-gripped by Miriam. "I'm right here," she reassured him. "I'll make sure you guys get there safely, I promise!"
And she did just that, releasing his hand and helping her father clear a path to the bus nearest them. Most of the infected were distracted by the madness going on inside the Hall, so the trip to the nearest bus was actually easier, and less incident-filled than she'd thought it would be.
Before she got on herself, though, she had to – had to – do one more check for her mother. She knew for a fact that if roles were reversed, Mary-Ellen would not stop for anything until she'd found Rae, and Rae refused to put in anything but her best effort. "I'll be right back. I have to find her," she called out to the others. She pondered adding, "if not, I'll see you at wherever they're taking us," but thought better of it.
She didn't get two steps, however, before she spotted Mary-Ellen making her way out the same window that the rest of them had gone through. Rae breathed out a desperately relieved sigh, not taking her eyes off the woman for a second as she took a couple of steps backward, toward the bus. But really, she should have been paying more attention.
The leaper snuck up out of nowhere and dove at Mary-Ellen when she'd been focused on shouting to tell Andreas that she was safe. The noise Rae made when she saw the scene unfolding was a horrible combination between a scream and a gasp. She made a move to shoot the leaper off her mother, but it didn't do much good as a group of runners made to swarm the window and completely blocked Mary-Ellen from view. "Dad! Dad, mom's in there somewhere! We have to-"
Andreas was ahead of her, though, and he moved to take a couple of steps forward to help his wife. But that was as far as he got before the call of "INCOMING!" came from a nearby rooftop. And the swarm of infected, the window of Carnegie and Mary-Ellen Alghren were swallowed up in flames from a haphazardly thrown molotov. "NO!" she screamed, moving to run forward and try and get her mother from the growing wall of flame.
