Looks like my mind decided to go totally blank for a while today... took me a while to realize the missing BI and ACE (great themers, loved DORASBOX58A*Trove found by a cartoon explorer?[--------]). The NE tripped me up - I totally overthought the ASPS10ASnakes along the 4D[----] clue seeing "snakes" as a verb, and I immediately knew that 12D12DContract signed before forming a union?[------] was wedding-related but couldn't think of the word PRENUP12DContract signed before forming a union?[------] for the life of me. SAVEME11DText that might be sent during a bad date[------] is probably my favorite clue-answer pair, and the math geek in me really liked PLANE52DWord after inclined or complex[-----]. Really fun solve overall!
