Scara has been your friend for 7 years in hogwarts and deep down you two have had a deep connection between each other.

Until lord Voldemort had returned and had started to recruit all of the slytherins for war. It wasn’t all worried until the day of the war. You and Scara had to duel to the death.

Other people might not be bothered by it but you two didn’t had the heart to hurt each other. Due to the pressure Scara was in, he ended up hurting you first. Sending a lighting to you.
