He had to turn into his beast.
Xavier had a hard time believing in it but Adeline had forced him into turning into his beast just to find her.
He had to turn into his beast form because of his human form who had hidden surprisingly better than anyone could ever have imagined.
When Adaline had run into the forest to hide it was early in the morning and it had taken quite a time for him to find her.
At the moment it was well over noon and he was losing hope.
He could only sense her half a way through after going maybe 15 to 30 steps into the Jungle he could not scent any smell of her.
For a moment or two it felt like she had disappeared into the thin air.
How the fuck did she managed to pull it off?
But since she had now he had been constantly walking around the forest sniffing around so that he could get a bit of a scent and follow it.
