Amanda~ Welcome to my story!! And thank you so much for leaving feedback!
About the time travel and interaction between the two Snapes. . . I've read lots of fics where Hermione is sent to the past, and as much as I love them (because I really do, A LOT!!), I wanted mine to be a little more original (I have this thing about being different when it comes to things like this. I'm always paranoid that people will think I stole their idea. Stupid, I know, but that's just how I am.), and I haven't read any that had to do with someone being sent to the future. (Wait, I take that back, I read one where the Marauders had been sent to the future and James met Harry's kids, and Lupin met Teddy. I liked it a lot, but unfortunately it was abandoned and deleted)
Anyway, back on topic! Where Severus had been sent to the future and not the other way around, there would be no way to keep everything about the future a secret. Which is why everyone is so strongly cautioned when it comes to time travel in the first place, so they don't learn too much about the future, right?
I did wonder briefly about whether or not I should try and hide them from each other, but I thought it would be more interesting to have them know one another. Besides that, Severus knows that he was sent to the future when he was young, and his younger self isn't stupid. Dumbledore could have sent Severus away, but the students would be buzzing if their potions master suddenly took a three month (and fourteen days)

holiday, and they would wonder aloud where Professor
Snape had gone, unless Dumbledore would have informed the students before hand, but even then, talk would be sure to ensue about the matter, even if Dumbledore had sworn the students to silence. So 'Alastar' would have figured out what his future career was to be anyway.
I suppose I just saved myself a chapter or two of Alastar figuring everything out and gave him more time to just be with Hermione.
Anyway, I hope I didn't confuse you with that incredibly long explanation, because I think I just confused myself.
As for the beta question; Nope, I don't have a beta for this one. If you're volunteering, I'd love to have you. It's always good to have someone go through my stories with a fine tooth comb, and to get ideas and feedback from. Send me an owl if you'd like to do it.
Thanks again for the feedback, Amanda, you're great!
hugs,

Dayna
