It seemed the Emperor truly was smiling upon her this day. Not only had he- or one of his followers, perhaps Sister Vitruvia or Confessor Horacio- managed to draw away most of the enemy's forces in one fell swoop, or so it seemed from the ever-so-slightly cracked door, but so too had Inquisitor Kliment seen sense in her plan and taken it to heart, announcing that Sister Lisbeth would be the one to take point, whilst Alexa followed on behind with the Inquisitor and other Sororitas in their task force. With utmost assurance that they would be safe in their actions, Alexa nodded at the Inquisitor's words, stepping forth to sally on beside him and her fellows, and then sprinting forth behind Vitruvia as she all but charged the installation - in stealth, of course. It was but a matter of due course that they eventually reached a nearly-unguarded entryway to the fortress, with but two men standing by and chatting about the day's events. Sister Lisbeth gave the order for the others to stay back, then stepped forward and... almost seemed to pause for a moment? And then levelled her weapon in the direction of the guards. Alexa's eyes widened behind the visor of her helmet; if she fired her weapon now, any semblance of stealth would be ruined! She had to stop the woman before she did anything stupid, she decided; slowly stepping forward behind Lisbeth, Alexa reached out ever so steadily, not wishing to scare her ally into firing mistakenly... And then the far-off hive city seemed to explode, and every single guard left in the keep seemed to go on high alert at the same time. Alexa was partly relieved, and partly shocked. Had that ruined their stealth advantage? She wasn't quite sure, and whilst it was rare for an Adepta Sororitas to feel overwhelmed, it did suddenly feel as though everything was happening at once, requiring a couple of seconds to adjust to the change in circumstances that could have proven lethal in, say, a pitched ambush. This, perhaps, was why Sister Lisbeth had been put in charge. As if to further the internal point, Lisbeth beckoned for the group to follow on, and quickly chased after the shorter woman on foot as she slid behind a pair of waste barrels, ruining her good robes with the muck of the place. Honestly, was there any reason she had to do that? It was frivolous to an extreme. Either way, Alexa's weapon remained ready in her hand, sarissa in place to slay any foe who might pass near their group, and weapon primed to fire if necessary.
