Audio problem: As Radar sets the clock back to 4:30, you hear ticking. The clock is electric, and wouldn't make a noise like that.
Suggested correction: Electric clocks do not necessarily lack a ticking sound. Depending on their construction, they may or may not have it. Older clocks are actually more likely to produce some sort of audible ticking sound, because the precise motor speed regulation required to build a clock with sweep seconds is much more difficult than producing an oscillator that outputs precisely one pulse every second (even if the clock in question does not have the actual second hand, that would still be true).
I bow to your observation and stand corrected. Thank you.
