It's Jane's (Jaimie Alexander) birthday on Blindspot this week - at least according to Weller (Sullivan Stapleton).

In this exclusive sneak peek of Monday's episode, Weller surprises Jane with a gift, revealing that it's her (aka Taylor's) birthday. However, the sweet moment is complicated by a confusing memory of Weller that resurfaces for Jane this week, all while she continues to grow closer to Oscar (Francois Arnaud).

Check out the full clip below. Blindspot airs Mondays at 10/9c on NBC.
