Before the second task.

It was before the second task and Fleur was trying to get as much information as she could.

She was already informed that it involves the lake but that was all she knew. The egg was in her hand as she made her way to the Hogwarts prefect bath.

She had convinced one for the password. Sure she could have used one in her carriage but she had heard the bath here was incredible.

After using the password she let herself in. Fully ready to relax and learn what the egg had to say.
