In time of need ( Aliki'r Quest)

[Dorabella]

This mission, available only after killing the dragon at the Observation Tower , will put you on the trail of a woman: Saadia

You will find Aliki'r at the entrance of Whiterun, who will ask you to find a person .

Go to the Barded Mare (Whiterun), and you will find Saadia in the kitchen, tell him that someone is looking for her. Follow her to her room for a private interview and, from here, you will start making choices.

Continue the dialogue until he tells you to go to the prisons to talk to an Aliki'r .

Found the guy, he will offer you to pay the bounty (100 septim) in exchange for an information: Where is Kematsu hiding . Pay the bounty, go back to the prisoner and then go to the Rogue's Lair .

Make your way to Kematsu, talk to him . Make your choice. Listening to kematsu, or killing him, along with his followers: And yes, he is not alone .

The mission will be completed in both cases.

If you decide to listen to Kematsu, take Saadia to the stables. Watch the Saadia / Kematsu dialogue and, here the bug starts.
At the end of the dialogue, Kematsu will cast the Paralysis spell on Saadia but, often, will not trigger. Which will lead Saadia to attack us .

To avoid this, the solution is to equip ourselves with the Calm spell , and throw it on Saadia. This will prevent it from attacking. 

For this spell to take effect immediately, make sure you have a good rank in the magical class you belong to. If so, continue throwing until you hit it with magic
