Who Is the Father of Hannah’s Baby in ‘Kaleidoscope’?

In a recent Reddit thread, one fan posited that the father could be FBI agent Samuel Toby (Bubba Weiler). According to this theory, Samuel is noticeably dodgy about putting himself in danger. After the death of his partner, Nazan Abbasi (Niousha Noor), he is also seen packing a stuffed animal, something that he might offer a child upon seeing them.

Another person posited that the father was the son of Roger Salas (Rufus Sewell), though another person rebutted that he was far too young.
