The line comes from Resident Evil 2 Remake, released in 2019, during a confrontation involving Umbrella scientist William Birkin, creator of the G-Virus. Cornered by operatives who want his research, Birkin treats the sample as the result of his entire career rather than company property. Fans of the remake clipped the exchange because his delivery sums up his obsession in a few seconds. It has since circulated among Resident Evil communities as a quotable Birkin moment for edits, streams, and fan compilations.
