Its based on grief and its a shared grief that they have, Reid teases.

It will really come into effect in the back half of the season.

Ahead of Dorys return, the Shaw brothers will reunite during a case involving UFOS.

Theres a secret that is revealed about their father that lands with both brothers, Reid says.

Theres a memory youll see that Colter doesnt have that his brother does about Colter and their father.

Now that the brothers are on better terms, they can actually compare notes and make some progress.

Hartley is excited to have his friend back as Russell.

Jensen came and he enhanced [the character] in every way.

[Velma] and Teddy have separated.
