Working for Daniel Whitehall
Lingenfelter and her team of scientists had been charged by Daniel Whitehall, the leader of a HYDRA cell, to find a way to duplicate the powers of the Obelisk. Using supplied cell samples from a victim of the Obelisk, Lingenfelter and her team believed they found a way to do so. Whitehall decided to test the method at the wedding of Pete and Mariah Leitner as many who attended were HYDRA’s enemies, as they sent in a HYDRA team disguised as waiters to poison the champaign with Lingenfelter's weapons, which had then resulted in the deaths of eight people attending the wedding.
However, the results were not to Whitehall's liking, since a few of the wedding guests and United States Navy officers died from the result, whereas Whitehall had believed that the Obelisk should be capable of more devastation. Later, Whitehall gathered Lingenfelter and their top scientists to voice his displeasure over the failed demonstration, questioning their teams about where they believed Lingenfelter went wrong, which scared her. Jemma Simmons claimed that Lingenfelter did not fail, but had assured him that given more time to study it, the Obelisk could then be used as a weapon of mass destruction.
