Alexa nodded to the Celestian's order, taking the back row of the column next to one of her fellow Battle-Sisters. Her lot was not to lead the charge, but to ensure those who did could do so without fail; and so she followed on, keeping her eyes forward, save when she glanced back to ensure they were not flanked - and, in one brief moment of distraction, toward the blade wielded by Sister Lisbeth. What an intriguing weapon for her to bear. Alexa wondered if she might discuss the matter with Lisbeth later.

But, that would be later. Now was a matter of combat - and rescuing their Crusader comrade from otherwise-certain doom. She thanked the Emperor, then, when their column finally reached him, imperiled but nonetheless living. In corridors such as these, avoiding gunfire and enemy attacks would be all the more difficult, not just for the armoured Sororitas, but also for their foes - a fact Sister Caroline made instant use of, opening fire into the mass of bodies with a hearty war cry, and heralding the echoes of gunfire that shortly followed. Alexa, without proper view, did not open fire immediately, but instead paid close attention to the battle to see who might require her help.

First to be injured, perhaps inevitably, was the unarmoured Confessor. Though his weapon was emptied into the crowd of heretics almost immediately, and his Rosarius flashed with every round that it deflected, it could not prevent him from coming to harm eternally. Under her helm, Alexa offered a sympathetic wince as what seemed to be a full quarter of his face was turned molten by a burst of lasfire; yet even as she moved forward to give her aid, the man recomposed himself and charged into the mass of enemies, bolt pistol and power maul to hand. She hoped he would be able enough in such circumstances to survive, despite everything he had going against him.

Her fellow Sisters seemed able enough: Sister Caroline's heavy bolter held strong, whilst Sister Vitruvia maintained weaponfire against the enemy until she ran dry of ammo, only to switch to her chainsword as the fray of close-range combat fell upon her, rather than the other way round. By now, Alexa had managed to pull forward enough to fire at her foes; bolt pistol in hand, she took aim and offered a triple-burst up to the foe, two rounds fragmenting a human's torso and covering his ally with viscera, and the third rending that man's arm from his body in a spray of blood. A second burst finished the foe off, then continued on to execute a duo of Kroot warriors, further back than anticipated. A mutant's solid projectile fire flew past her allies and zinged off of Alexa's armour like rain; the third burst was dedicated to his execution, and happened to catch an extra mutant or two in its deadly arc in the process.

Now Alexa reloaded, swapping her current bolt clip for a fresh one, and again looking to Sister Vitruvia - just as she finished off a Kroot warrior with a vicious blow to its neck, though she took a heavy hit to her back in the process. Her armour was sorely dented in many places, and it was clear she'd taken at least one serious wound. Yet, or so it might seem, she insisted through wordless action that she needed to continue her fight. And... where was the Confessor? Damn it all, he'd vanished! Where was he, where- ah, no, he lived yet, though kneeling in a side-room with a Kroot's mangled body at his feet, it was clear he ailed at the present time. Alexa made her way to him, muttering 'Let me examine that injury' to him as she entered, just to ensure he didn't lash out at her unnecessarily.

And the injury itself was, honestly speaking, a rather gruesome burn, flesh blackened and melted away almost down to the bone. Yet despite this, it was essentially cosmetic for the purposes of combat effectiveness - the man was winded through his own exertions rather than the pain in his face. He would, however, need more in-depth medical care once this crisis was through; in a field situation such as this, there was nothing Alexa could offer to help such a wound, other than a couple of injections - an analgesic at the injury site to relieve him of pain, followed up with an antiseptic spray to ensure it remained uninfected until proper attention could be given; and a stimshot to the arm to restore his energy levels. His assistance was greatly appreciated, of course, but Alexa felt his age might hold him back again in the future. She'd perhaps suggest to him at a later date to ask about rejuvenat treatments, just in case.
