The Attack on Ellen Nadeer was an attempt by the Watchdogs to determine whether Ellen Nadeer was an Inhuman, which unexpectedly escalated into an explosion that killed many at the United States Capitol.
Due to her brother being an Inhuman, the Superior suspected that Nadeer could be Inhuman as well. Although Nadeer had secretly funded the Watchdogs since the beginning, the Superior could not bear being supported by one of the people he was hunting. Therefore, he sent Tucker Shockley to Nadeer's office with the mission of shattering a Terrigen Crystal and seeing if it triggered Nadeer's Terrigenesis.
Tucker Shockley went to the United States Capitol, taking a shard of a Terrigen Crystal with him. He entered Senator Ellen Nadeer's office and they discussed Nadeer's commitment into the anti-Inhumans cause. Shockley then explained that there was a possibility that Nadeer had dormant Inhuman genes in her DNA just like her brother did. Enraged, Nadeer ordered Shockley to leave her office, but he refused and shattered the Terrigen Crystal he had brought.
A Terrigenesis effectively occurred, but not for the person Shockley expected. Indeed, instead of Nadeer, he underwent Terrigenesis himself and screamed in horror as the husk enveloped his body. Nadeer laughed and began insulting Shockley, claiming he was disgusting. However, Shockley could not control his newfound exploding powers and cause Nadeer's office to blow out in a massive explosion which killed Nadeer, her assistant Zach Bynum and two other people.
