Putting Molli's make-shift sling on sent a surge of pain as adjustments had to be made with the arm's position, but Sif just had to grit her teeth. There was relief as the sling cradled her "wing" as Molli would put it, though by this point, she started to feel numbness in her lower arm, particularly the fingers. She wasn't afraid of losing an arm to this as the femtomachines would work its magic so long as the limb stayed intact, but the way she was now, she wouldn't be effective in fighting off security. Especially with her trusty pipe left behind. "Thank you, Molli-sama," she'd say with a nod, the closest thing to a bow she could do in the situation.
When they neared the exit, the captain let her down from the gravity field. As for how she understood 'getting that fighting spirit back', she took that as getting herself back into fighting condition. She recalled that one-off demonstration from training, and a shiver went down her spine. It was made clear that such things should be done by people with the proper training, but that option was not always available. But they were nekovalkyrja. What's a bad set compared to a hailstorm of bullets.
She went to the front ahead of everyone towards the door as she was unarmed, and dropping to a crouch, Sif slid her arm out of the sling and put her hand palm-up and flat on the ground and pressed the heel of the opposite foot down on it to keep it in place. She breathed in and rapidly repeated a simple mantra to herself: "Relax." As she did so, she pulled her upper body backwards, her other hand on her dislocated shoulder helping to guide the joint back to its socket. There was a loud pop followed by a crying whine and a gasp. Warmth rushed down her limb, feeling like electric prickles when the rush went to her finger tips. The relief was instant, though a few nerves were still stinging.
Sif got back to her feet and dashed towards the exit, throwing it wide open. As she dashed out, she looked to her left, then as she came to a rest on the opposite wall, and slightly to the right with a gentle thud, she looked towards the opposite end of the alley, looking for any other threats to their safety.
