Trisha Delaney

Trisha Delaney was the sister of Rob Delaney.

Jackie Tyler suspected that Trisha had been badmouthing her to Tycho Fairbank behind her back. (AUDIO: Retail Therapy)

Rose Tyler knew her as "Trisha from the shop". Mickey Smith claimed to have started going out with her when Rose was gone for long periods of time with the Ninth Doctor. Rose, however, knowing the two of them and thinking "that's never gonna happen", thought Mickey was using Trisha to get back at her, and that "It's got nothing to do with Trisha." Nonetheless, when Rose returned to 21st century Earth in the TARDIS and "pick[ed] up the phone", Mickey said he came running for Rose and would "sit here for the rest of [his] life waiting" for her.

One Wednesday in 2007, when both Rosita and Yasmin did not answer their doors for a bit of gossip, Jackie had to resort to calling on Trisha Delaney. Jackie found that all of her neighbours, including Trisha, had gone missing. She first suspected that they had all gone on a girls' night out without her. In reality, Trish and the others were being isolated from N-Space by the Harvesters in their plot to lure the Doctor and Rose. (AUDIO: Wednesdays For Beginners)
