The worst part is, part of her had been sure that she could have stopped this.
She couldn't have. Qui-Gon Jinn simply has no fear.
And she does still think it's 'has', for all that it's no comfort when she sees the body.
There was a Force bond. There still is one. It's just not the same, now.
She doesn't mention it to the Order.
It's not relevant to the investigation.
She does mention the discussion she had, that C3PO recorded.
She does not mention the formless dread she'd felt, or the last words she'd said to him.
I'd be worse off without you.
How true that is. She's cold, inside. A sickening, dreadful feeling of emptiness as one of the few bright lodestars that are ever true to themselves winks out.
She sends a comm to Padmé, sneaking it through the firewall: QGJ assassinated in broad daylight just now. Be vigilant. Trust no one except probably Jedi. S wanted Q alive for Coruscant. Who benefits?
She holds her mother close, and tells her to stay inside the Temple's walls; it's quite possibly a matter of life or death.
She sends a message to Yoda; I had spoken with Master Jinn about this, but unfortunately, he was assassinated before he could pass it on. I'd like to speak with you sometime, about why I believe you were teaching the wrong lesson in meditation class - I suppose it's still today, now, even though it feels like it's been a week. I am a bit frustrated that you did not engage with my questions in the spirit they were asked at the time, but I wish to clarify that I hold no particular ill will towards you. Sincerely, Kina Skywalker.
She sends a message to the Jedi High Council, via droid-delivered sealed flimsiplast: I have enough information on the Sith Lord that it is worth presenting to you so it can inform the Order's investigations; I was planning on bringing this to your attention through Master Jinn, but he was assassinated today - either in retaliation for his prior interference, or to directly impede the progress of this mission. Please schedule a secure meeting as soon as possible.
Sincerely, Kina Skywalker.
Then...she heads for the armory. She has a basic fact of geometry to exploit, and some tinkering to do, though it will bring her no relief.
Whatever Sith Lord arranged this will be ended neatly. It's the least she owes him.
