Secunda sighed with relief. Yes, her thoughts were slower, but there is little value won through bemoaning muzzle velocity as long as you hit the target. This one hit at least a couple of decades ago, ever since a particularly gruesome combat simulation revealed Tiefebronn's flaw. 

His miniature militants fought to the bitter end on the simulated battlefield as they got crushed, stuck between Passivity maniples and November skitarii. He took pride in the heavy toll he managed to inflict before going down. At that moment, Tiefebronn - brilliant, bedazzling, ruthless, ambitious - Magos Tiefebronn exposed his flaw, fully formed through his illustrious career. He was a winner, first and foremost. That pushed Toros to question "What would that mind be like if less accustomed to blasting through every problem?". 

The flawed clone presented her with a rare opportunity to have this answer at hand. Trying to beat everyone else in the race to the Throne would've been too risky - not enough resources, not enough adepta ties, not enough years of existence... Too weak to be a king, too smart to be a puppet. She guessed that Stoll would make the right choice here, growing more confident there when she did not see an incoming request.

Necromechanic could not be a king, so he strived for the next best thing, sitting as a kingmaker and toying with the unearthed aces up his dirty sleeve until he figures out who's the highest bidder. He sits there and ponders the old stories - stories she told him - about the nature of things, for he is in no rush. Of all people, he knows that immortality is a proper tech-prayer away, and of all people he knows that unlimited time comes with its costs. Such as being called names.

"Not sure about this whole 'stranger' thing, Magos Stoll. Not from you, of all people. I am no stranger than you, and definitely not among the strangest dead things coming alive in your experience, o esteemed archaemancer.", Secunda carefully accepted the bio-auspex, starting sampling blood over the lab and eyeing the bolt-casings around. "After all, even as you might debate that the ship is not the Themis original, you cannot really say that it is different enough to be completely new to you, practically speaking. Even if its light is yet to rekindle to the pyre of old, the shade is still the same." 

On the side-note, Secunda was pretty sure that Stoll did not have a niece for Tiefenbronn never cared to sire a daughter for reasons political and biological. She was also pretty confident that if he did secure himself some progeny, he would prefer personally extracting skulls from them in case they decided to hang out with Stoll. It would appear that either times have changed or... She preferred not to delve on "or" here.

"Speaking of pyres, resurrections, and theology, it is my humble pleasure to formally introduce Sister Kota of the Sacred Rose, who, and I insist, just so happens to be the best thing that Omnissiah decided to introduce into my life so far. Sisterhood customs related to martyrdom and subsequent rebirth are among the ones tragically underestimated by the tech-clergy at large.", Toros rose to her feet, putting the sampler aside. "I skimmed the top layers of the concept a century ago, directly inspiring our strange lives, Magos Stoll. Still, I am sure, Sororitas could bring some more... unexpected... angles to the Ship of Themis conundrum."

Secunda wondered if the rusty terminal would try to bring up that old M36 memo, the spark at the start of the whole thing. She prayed to the Godhead that it would not. It would not be becoming to get murdered right after getting saved. Having caught herself biting her lip, she turned away from the terminal and into the nanoscope array.

She was able to clone herself in vitro from a spare rib and a gallon of blood. She should be able to figure out what the Trespasser has been, even if she had just a couple of spatters to work with.
