Mary Lou's lovely Thursday exercise got me with LACT_/SAM_. I didn't know SAMI but had a good feeling about LACTO. Her LOW KEY theme used the gimmick that the word KEY could be appended to the last word in the four down fills with asterisks to form a common phrase. The first word of the amended phrase was also LOW on the vertical fill and so LOW KEY!
