Watt Bennet said this with another purpose in mind.
Announcing this in front of so many journalists, his main aim was to inform Ryan Walyon and Manuel Ink that Summer Sutton was his wife, legally connected to him, thereby claiming victory over the two of them.
Of course, confirming her status as the legitimate partner in front of the public was also a reason.
Watt wanted to clarify to everyone that the only woman associated with him was Summer Sutton, and others had no relation to him.
Does this put an end to all the journalists' doubts?
After all, regarding that night's incident, the journalists only knew Watt was spotted near Lorraine Hughes' house blocking a car, unaware of other details.
Despite his statement aiming to suppress any speculation, unexpectedly, the car window rolled down with Summer's voice gently drifting out, "Mr. Bennet's declaration isn't truthful; the matter of obtaining a marriage certificate does not exist."
