Weller's dad's days are numbered on Blindspot.

On Monday's episode (10/9c, NBC), Weller (Sullivan Stapleton) learns that there's nothing to be done to save his father, Bill (Jay O. Sanders), who has lung cancer. "He's not going to make it," he tells Jane (Jaimie Alexander) in the exclusive sneak peek above.

"Maybe you can take me to meet him sometime," she replies.

So will Jane finally speak to the man who was accused of kidnapping her 25 years ago?

Check out the rest of the clip above.

Blindspot airs Mondays at 10/9c on NBC.
