|“||God's name... an army of Ashes?||”|
Presumably this version of Sheila had a similar experience with Ash like her film counterpart (falling in love with Ash, getting kidnapped by Evil Ash, ect.).
While watching Ash ride away to return to his time, Sheila was approached by Lord Arthur and The Wise Man about helping them create a team of select individuals to carry on the teachings of The Promised One incase the Deadites attacked once more. Sheila agreed to become a teacher for the organization that would eventually become the Supernatural Military-Adjacent Response Team (or S.M.A.R.T.) by the 21st Century.
