The visual distinction between realities becomes clearer, with Frolov tracking his state through markings on his wrist (a cross for one world, a circle for the other). Critical Reception and Highlights

Frolov notices that clues from a case in one reality often provide the missing link for a different case in the second reality.

The episodes highlight the "double grief" Frolov experiences as he attempts to comfort a mourning wife in one world and a resentful, grieving son in the other.

Critics and viewers generally praise the 2021 adaptation for its high production quality and the lead performance.
