Maeve Griffiths

From Tardis Wiki, the free Doctor Who reference

Maeve Griffiths was an old lady living in Elderberry Close when the children started to disappear in July 2012. She talked to Trish Webber, saying it was not safe. When Maeve crossed the road and warned a father to take his children inside, a child called Tom disappeared.

She later encouraged the Tenth Doctor and Rose Tyler investigating the disappearances, cluing them in that it was a supernatural force was responsible. When the children reappeared, Maeve thanked Rose, and told her to extend her gratitude to the Doctor for her. (TV: Fear Her)
