BOOM

"BOOM" is the thirteenth episode of the fourth season of the ABC/Marvel series Agents of S.H.I.E.L.D. and the seventy-ninth episode overall.
==Synopsis==
Daisy, Mace and the S.H.I.E.L.D. team must find a way to contain an explosive Inhuman. Meanwhile, Coulson and Mack come face-to-face with Radcliffe’s inspiration for AIDA.
==Plot==
Coulson and Mack locate Agnes Kitsworth, Radcliffe's former lover and partner. Radcliffe left Kitsworth after she was diagnosed with terminal cancer, and modeled AIDA after her. Coulson convinces Kitsworth to meet with Radcliffe. In case Nadeer is an Inhuman like her brother, Ivanov sends Watchdog Terrence Shockley to expose her to Terrigen (provided by Radcliffe), but the substance transforms him instead. Shockley explodes, killing Nadeer, and then his molecules reassemble. Ivanov agrees to use Shockley's new ability against S.H.I.E.L.D. Radcliffe meets with Kitsworth and convinces her he can save her life if she escapes with him before S.H.I.E.L.D. captures them. Johnson confronts Shockley, and distracts him long enough for Fitz and Simmons to contain him in a specially-made device. Ivanov uses this as a distraction to attack and kidnap Mace, who has learned that each time he uses his super-serum there is a chance that it will kill him. As Kitsworth dies of the cancer, Radcliffe places her consciousness in the virtual "Framework" with May.
