At first Simba and Nala were uneasy about letting Falcon into the pride and accepting him as Dusk's chosen mate, initially she was betrothed to one of the young male's that was the son of family friends but being only an adoptive daughter the betrothal fell through and as Dusk became more adventurous Simba began losing hope.
He decided that he would temporarily give Falcon a chance but naturally, as Dusk was not yet adult, she had her tantrum and threatened to leave for good. With Nala's final approval and some convincing of Simba- Falcon was chosen as Dusk's mate and in line for the throne behind Kovu.
