Danny Reagan was a one-woman man on Blue Bloods until the death of his wife, Linda - and that's when fans began rooting for him to find someone new. While Danny's (Donnie Wahlberg) work dynamic with OG NYPD partner Jackie (Jennifer Esposito), was strictly platonic, viewers were hopeful for a romance between Danny and second partner Maria Baez (Marisa Ramirez) not long after Linda's (Amy Carlson) death in season 8. However, it wasn't until season 11 that Danny and Baez's friendship started to become flirtatious.
