Vikra knew that once Adrianna stepped foot in the wizard kingdom, he wouldn't be able to touch her. So his only chance to abduct her was to catch her before she got to the wizard kingdom. Hence, it was important for him to know which route was she taking.
The neotides informed him that the entire group was going to fly back to the wizard kingdom. This was the loophole he had been waiting for.

Before leaving, Fleur wanted to meet Liam as not meeting him was making her sad. She wanted to see him and was unable to understand as to why she missed him so. Her logical brain wasn't functioning well whenever it came to Liam. She thought of sneaking around and finding Liam, but was caught by Ed.
"Where are you going?" he asked with a raised eyebrow.
She was taken aback by his question and said, "I was going to meet Father."
"But your father is standing right here," replied Ed, even more bemused. "You should prepare to leave."
