Jason receives a text message threatening to reveal his secret - but who sent it? Jason's search for the sender reveals there's a thin line between ally and enemy. Olivia, on the run from Ian, takes Cole to a place overrun with memories of an earlier life with his father. Closer to home, Jordan's investigation into Jason's past turns up a promising lead.

When a surgery's complications force it to continue after 8:25pm, Jason chances taking Ruben's still-unfinished kill drug to hold Ian off long enough to finish the surgery. The surgery is a success, but the drug doesn't last as long as planned and both Lena and Olivia suffer as a result.
