cos Wiki is gone maybe some info should be shared ....
With Ysera, for this we go to the bench on which the Huntress was sitting (only if you didn’t return her bow before the fourth day!) There is a coin on the bench, we go to the very top of Sylvanas’s mansion, there is a box, open it with the key that was on the second floor of the club and take another key. With this in the key, you need to go to the naga, this naga is in the river (We go into the river and swim towards the house of Ortell, it will be behind one of the stones on the left side). We give the coin to the naked and open the door with the key (If it doesn’t work, then hold down CTRL to dive deeper). We are watching the long-awaited scene with the sleeping Ysera.
1)During the second night (The day when Alex stole Azshara's panties) you need to find the boat near Inna's hideout (Death Knight's hideout on the map), on which the fishing rod lies, take the fishing rod.
2) During the third night, before talking with Elena in the guest house, you need to go to the pier behind the draenei house, use the fishing rod on the pier and catch the cassette.
3)After Alex drinks Ireola's potion, you need to go to the cemetery, there is a key on the central grave on the right, we take it.
4) We go into the house opposite the house of Boruga, open the door with the key and use the cassette on the TV. But I warned you that it's not worth the effort.
