Hi

I remember Clark hearing messages sent on a frequency only he could hear, but I can't remember which episode/s.

Anybody help?

TIA,

Corrina.

The only episode I remember it in is "church of metropolis" when the lawyer is warning Superman to stay out of the south side.
Were there any others?

There's also "We Have a Lot to Talk About..." where he hears the warning that if he moves, he'll set off the bomb.

I think wall of sound used that as well

"The Family Hour" when Mensa had a message broadcast to Superman that his family had been captured.

Also there is Jimmy's ultrasonic signal watch in "The Green Green Glow of Home"

Alt-Clark could also hear John Doe's message during "Lois and Clarks". I can't remember if he could hear both the phone line and power line messages or just the power line one.

Wasn't there also something like that in the first NK episode?

Sort of. I think that was supposed to be telepathy but I don't know for sure.

Yes, you are correct. That was Kryptonian telepathy.

Thanks for the pointers, everyone. I'm not strictly following canon, but I wanted to be reminded about how and when the show used this method for communicating with Superman.
