Comatose

When Shining Armor and Cadence's love shockwave vanquishes the Changelings, before being sent away Queen Chrysalis fires a poisonous beam at Twilight's chest that leaves her in a comatose state she might never wake up from. As the doctors fail to find a cure, and everypony starts losing hope, Shining Armor is determined to help Twilight return to them, but on the inside he is conflicted by the cruelty he mustered at her the night before and his failure to ask for her forgiveness before being shot. Shining won't be able to live in once until Twilight says she forgives him, but how can that be when she can't probably even hear him?
Will Twilight wake up and go back to her old life, or will Shining Armor's tortured memory forever haunt him?
