Donna (Goodwill Toward Men)

From Tardis Wiki, the free Doctor Who reference

Donna was a volunteer at the Los Angeles Midnight Mission. She was homeless at one point, but once she found a home she continued to work at the mission.

When the Second Doctor, Jamie McCrimmon and Zoe Heriot arrived at the mission, Carl sent them to Donna to direct their volunteer activities. (PROSE: Goodwill Toward Men)
