Next, the ship is absorbed by the green cloud, and we get our title card.
Below, we see Varian (Jared Martin), the man from the 23rd century.
The images introduce his tuning fork instrument as well, a tool on the series that operates much like the Doctor's sonic-screwdriver on Doctor Who (1963 -1989).

Next, we meet another character from the 20th century, young Scott (Ike Eisenmann).
At least one image in the tri-part frame below stresses his connection to philosophy by surrounding him with Greek pillars.
