The Thirteenth Doctor in her emergency transmission. (WC: Message from the Doctor)
- You may be looking for the emergency transmission created by the Thirteenth Doctor.
TARDISes were capable of sending emergency transmissions.
The Thirteenth Doctor created an emergency transmission in which she listed 5 things that she did in any worrying situation in order to encourage the recipients to do the same thing. This was sent out by her TARDIS because it detected an upsurge in psychological signals from somewhere in space and time. (WC: Message from the Doctor)
