 In the preview for the "TV version" of episode 22 (broadcast before  the "directors cut" was produced), subliminal messages written in  multicolored text on a white background are rapidly flashed on the  screen. These were actually not used in the TV version and were  relegated to the extended "mental attack" scenes added for the DC  version. Interestingly, the preview for the DC version features  subliminal text written in white over a black background, which  appeared in both versions.
