Regret is all Sera has ever known since the day she broke Shade's heart.Now she realized her mistake...but she has no clue where Shade is.If she hadn't betrayed him,what could've been?She wondered this as she touched an Animus-touched mirror.Then the mirror showed her what could have been---had she not hurt Shade,they would have been together forever.They eventually would have had dragonets---one female with the same powers as Shade minus the berserk mode,and one with that berserk mode but no special NightWing powers.Shade would have been completely loyal to her,and it WOULD have been perfect.But as that showing of future ended,the mirror put up one message into Sera's mind.'If you hadn't broken his heart.' And then,more regret pooled out of her than ever.Because now she knows what possibility she had shattered.And she had one emotion when that possibility had been shown.Regret.
