I appreciate it, I'm glad it did work out for you! Hopefully it just works out for me too because I also don't have any back-up plans, I don't even have a phone number for this person, and considering it's Saturday I don't think they'd respond to their office phone anyhow.
I am still good friends with an SLP who once was my field placement supervisor, so she did technically grade me, but I don't think that's nearly close enough to count as an academic reference. Just crossing my fingers now that my current reference does respond.
