@SebastianEl "return" will end each dialog option and go back to the start point, so it should stay at the end of each option. Just take that first "return" out and leave the second return in, and see if that works. When adding a new dialog option, you'll see AGS adds a return automatically. The dialog should go after the and before the return.
