I usually get so tense and worried reading time-travel fics (as much as I love them), but you addressed it in such a novel way that I enjoyed it anxiety free. I like that you mentioned the AU aspect, so that his friends' lives wouldn't be changed, but Sev's could. The moment when Hermione discovered Harry physically missing was an eerie one, but what a punch! I loved meeting young Severus, and the developing relationship was great. I really enjoyed their first encounters. So rough and ignorant, just following what feels good. Well done, and a fine read. I can't wait to find out who wrote this.
