It turns out that Harry’s clients have needed information on Season 3’s big bad — a “nefarious arms dealer” known as The Widow.
Harry just might be the key to making sure The Widow doesn’t get what she wants.
Sebastian (David Lim) was holding Harry (Russell Tovey) at gunpoint the last time the Quantico team saw Harry, but Sebastian ultimately let his former roommate go.
That was supposed to be the end of the road for Harry, but he’s rejoining the team in a big way in Season 3.
