Neural relay
From Tardis Wiki, the free Doctor Who reference
Neural relays are devices used in the 51st century to let people send "Thought-Mail" by Point-And-Think Technology. Sometimes, if someone dies, their consciousness may still leave an imprint in the neural relay. Using its comms device, the Data Ghost is able, for a short time, to talk to other people, before deteriorating, starting to repeat itself. While usually lasting only a few minutes, Anita mentions that her Grandfather 'ghosted' for an entire day and kept talking about his shoe-laces.
- Miss Evangelista's data ghost wanted to talk to Donna, but deteriorated to repeat "Ice Cream."
- Proper Dave's, "Hey, who turned out the lights?"
- Other Dave's "We should go, Doctor!"
Anita was killed by the Vashta Nerada, but had no obvious Data Ghost, as the Vashta Nerada had learned to talk through the neural relay.
