Hands up if you're in a full-blown panic about the mysterious letter Bachelor Sean Lowe receives just moments before popping the question to either Catherine Giudici or Lindsay Yenter. We can't even tell you how many freshly deep-fried armadillos we've stress-eaten in anticipation of this handwritten note, and fans won't find out who sent it to Sean until next week's Bachelor Season 17 finale!

Bachelor Nation has been speculating that the note was written by either Sean's second runner up (in a final plea for his affection), or his mom (encouraging him not to go through with the proposal), but either way it sets off a "chain-reaction" the likes of which we've never seen.

"The letter sets off a chain reaction that doesn't end until the LIVE AFR," Bachelor producer Mike Fleiss tweeted during The Bachelor Season 17 “Women Tell All” special.  

Considering that the After The Final Rose special is live, we're going to assume that the contents of Sean's letter have remained unresolved — and you know what that means. ABC will bring out the letter's sender for an epic confrontation! As far as we know, Sean is currently engaged and happier than ever, so hopefully whoever wrote this letter won't try to come between him and his future wifey....

Who do you think wrote Sean's letter? We found out from an inside source!
