Brilliant!! I love Harry spending time with young Severus--and you did a great job of slowly developing both their relationship and the way Harry was able to be in two places at once. ;) I always love time travel fics and while this isn't precisely that it certainly feels similar. I wasn't sure what Harry would end up doing or whether he'd get stuck but more than Harry's choice I like that Severus ended up being able to make a good choice too. Really enjoyed this! Excellent work.
