Head to the Jedi Archives, it might be worth trying to save the data there

A Jedi Padawan, no more than 14 or 15 years old stands before you. Behind him, you can see the Jedi Archives.

"Master Skywalker, what are you doing back at the Temple?" the young Jedi asks you.

"Where is Master Shaak Ti?" you ask firmly.

"She's in her room meditating. She said she felt a great disturbance in the ****."

You hear an explosion go off in the distance

"Master Skywalker, what's happening?" the boy asks you in a frightened voice.

You finger your lightsaber hilt as you consider your options. If you striked him down, you would be noticed by the other Jedi in the Archives and would lose the element of surprse. If you left him alone, you could leave the Archives and search for the last Jedi Council member unnoticed.
