Monday's episode finds the bespectacled puzzle-solver trying to woo Patterson back by - what else? - planting a secret message to her near a coffee vendor. But, judging by the exclusive sneak peek below, he's going to have to do a lot more than that to pull Patterson away from what she describes as the biggest case of her career.
And it also begs the question: Is David really just a lovesick geek trying to win back the girl of his dreams? Or does he have a more sinister motive for trying to stay close to Patterson as she's working to decode Jane's (Jaimie Alexander) tattoos? You be the judge!
Check out the clip from Monday's episode below, and share in the comments whether you think David can be trusted.
Blindspot airs Mondays at 10/9c on NBC.
