Harbinger

The Coach, Jarold Sean, and Sarah Smith were celebrating Jarold Sean’s birthday and Sarah Adric Smith's graduation from the academy of Time Lord's on Gallifrey. While the party was still going The Doctor called The Coach leaving a message saying,* a Time Lord by the title The Alchemist has been messing around in event's in Skaro’s history, you need to find out what he's done, see if you and your family can undo what The Alchemist has done, and try to get out before you are detected by The Daleks in the future.”  Later when the dual party ended The Coach said,” I'm proud of my Son with Jameson Sean, and my step daughter Sarah Smith very impressed. Happy 14th birthday Jarold Sean and Sarah Adric Smith congratulations on graduating from the academy, your real Dad will be so glad to hear it.” Jarold Sean asked,” you know I look thirty six, but I'm glad my Dad's know my actual age so I can be applying for the academy soon right Dad?” Sarah then asked,” I'd like to have my own T.A.R.D.I.S can I go visit my actual Dad? So I can ask for a piece of his Ship to grow my own?” The Coach replied,” I have to think on those two things. Oh I have a message from my friend The Doctor.” After playing the message he set course for Skaro.

The Alchemist was making key elements for a machine that would help The future Daleks with a battle strategy, going to Davros with this invention and explaining to him how it works and Davros said,” I like it, but I don't need you.” The Alchemist then ran out and teleported away saying,” I only came here to get The Coach's attention I am The Alchemist and this has been a relatively good Interaction Mr. Davros.” 

The Coach had gotten there just before The Alchemist did, instructed Jarold Sean and Sarah Smith to put a Fail-Safe in the battle strategy device called Harbinger that would activate it if a future Dalek goes way to far even by Dalek standards. Quickly left off but not before getting a scan of The Alchemist with his Sonic Pointer. Back in The Coach's TARDIS (stuck in the disguise of a Morehead State University moveable locker as the exterior disguise) he got the readings from his scan of The Alchemist a little disturbed by what that could mean for him and Jameson Sean's relationship romantically he decided to brush it off for now.
