Alison Docherty

Alison Docherty was a woman in her late fifties and was a survivor of the 2008 Toclafane attack. In a vanished time line she feared that she had lost her son due to the attack. Tom Milligan took Martha Jones to her lab where she found out how Martha was going to defeat the Master. Martha said that she had a gun with liquids in it that could kill a Time Lord.(Martha made this he cover story to trick the master). When Martha and Tom left into London she had a secret television link to the Vallient where the Master stayed. She told the Master the whole truth on the plan. When that version of 2009 was erazed nothing had ever happened. She still worked a normal job Martha gave her flowers to say thanks but she did not know why.
