Sabine had only seen Stormtroopers cut down by lightsabers a few times in her life.
Once, had been in her earlier days with Kanan and Hera and Zeb on the Ghost. Kanan had let it slip to her not very long ago that he could use the Force and had his own lightsaber, he didn’t say the word Jedi which had confused her at the time since he obviously fit the definition. Not that it mattered that much, she was more concerned about if they were going to boot her off or worse if she failed them on a mission.
Coincidentally, the first of her few failings was the reason Kanan had to use the damn lightsaber in the first place.
She hadn’t seen the last trooper, perhaps because of a glitch in her helmet’s sensory suite, or all of the smoke, or just because she’d shot the trooper once already, center mass, with a Westar-35.
The trooper had staggered up as Kanan came running in, his blaster was overheated and useless from the sheer intensity of the firefight they’d been in. He arrived just in time to watch her turn in surprise at the stormtrooper and take a blaster bolt right to the plastron chest piece.
Beskar armor is tough and E-11s are just light carbines, but the impact knocked her back and down in an ominous spray of sparks while also cracking two of her ribs.
Kanan had swept into action almost instantly, blue plasma snap-hissed to life one moment and in the next the imperial was down with a glowing line through their helmet and chest.
Sabine wasn’t sure if it was her mind trying to fill in the gaps or just misremembering things but she swore she saw Kanan flick his gaze down to his blade before he deactivated it.
The second time she’d seen people killed by a lightsaber was when Kanan sprung from the bacta tank to save the day, she admitted to herself that she wasn’t sure if he’d had that same almost accusing look towards his weapon.
The third time had been with Ezra, running down a hall trying to rescue that dikut Hondo and his piggish friend. That time had been a clear sign that something was up, instead of just cutting through blasters and returning the burning red bolts to their senders Ezra had cut through them like training tatami cutting mats back on Krownest.
It wasn’t very long afterwards that she killed someone with the Darksaber. Unlike Gar Saxon there was no chance to allow the Super Commando to surrender, this was war and there was no room for deliberation.
She’d managed to wrong foot the imperial with a kick before bringing the Darksaber around in a horizontal slash that carved through corrupted beskar armor and deep into the imperial warrior’s chest, burning through bone, through meat and marrow and organs. Even through her helmet filters she could smell vaporized flesh and blood.
But that wasn’t the worst part.
Kanan had once told her that all of your emotions flow into the energy of a lightsaber. What he didn’t tell her she found out then.
When you kill someone with a lightsaber you feel them die, their soul or their Force essence or whatever Jedi nerfshit Kanan would say.
Unlike the detached slaughter of blaster bolt fire a lightsaber forces you to feel the life you’ve taken leave this Galaxy.
Sabine really wished she’d know beforehand.
(So I finally came up with a logical reason for Kanan and Ezra to just cut through the stormtrooper’s blasters. What do you guys think?)
