Chase is one of the dumber Millers....I mean every other Miller who has his own story so far seemsto be more intelligent than Chase.... I mean he actually knows Emma's full name. A few chapters ago she visited him as Keith Pittman's secretary. He should know that she and Josh share the same family name.
Spoiler
He finds out being Pete's father in the last chapter of the main story, before the epilogue...because Josh tells him. Before that Spoiler

When he finds out Josh being an omega, when he see the mark with the rest of the bodyguards...he doesn't recognize his own mark. He thinks an alpha woman, who is "Pete's mother" marked Josh. So he later begs that Josh stays with him and wants to become his own child's stepdad... .
He so dumb , I know he will find out about his kid in the side stories at this point
