Layla's location

Layla can be found sleeping at the Bimarstan Hospital in Sumeru City. Since she's sleeping, you won't be able to interact with her properly. That said, you can still use Nahida's skill on Tamara to see her wondering what she should do with Layla.

Use the teleport waypoint near the Adventurers' Guild in Sumeru City and go to the Grand Bazaar. You will find Alhaitham and Kaveh in front of a stall as soon as you pass through the bazaar door.

You can also use Nahida's skill on Alhaitham, Kaveh, and the vendor to see their reactions after their original interaction.
