Grey alien (Starstation to Starstation)
From Tardis Wiki, the free Doctor Who reference
A grey alien was among the inhabitants of the Bubble. When the police were searching for Iris Wildthyme for her involvement with Dovan Binderwall, the alien was wearing an identical hat to Iris's and was mistaken for her at a climactic moment. (PROSE: Starstation to Starstation)
At another point, when Iris was writing her journals at the Pair a Dice Cafe, the alien watched her from behind a bin outside. (GRAPHIC: Wild Thymes on the 22)
