Synopsis by Brian J. Dillard
Angel's ex-girlfriend, Buffy Summers (Sarah Michelle Gellar), arrives in Los Angeles to berate Angel (David Boreanaz) for skulking in the shadows in Sunnydale to protect her without making his presence known (see Buffy the Vampire Slayer, "Pangs"). In the middle of their argument, a demon attacks, and Buffy and Angel take to the sewers to track it. During the ensuing melee, some of the demon's blood mixes with Angel's and he's amazed to discover that he has become completely human. Now that Angel is free from the curse that will turn him into a bloodthirsty monster if he ever experiences true happiness, a blissful day of sex, love, and ice cream soon reunites the ex-lovers. Unfortunately, another demon shows up and Buffy must protect her helpless lover. Angel realizes that without his vampiric abilities, he and those he cares for will be in constant danger. He begs the two Oracles of The Powers That Be to turn him back into a vampire. They use a temporal fold to turn the clock back 24 hours, leaving only Angel with the memory of his perfect day with Buffy and causing everyone else to forget it ever happened. Originally broadcast November 23, 1999, on the WB network, "I Will Remember You" marked season one, episode eight of the supernatural comedy drama. In the Buffy episode "Something Blue," Buffy mentions that she saw Angel in Los Angeles for only a few minutes -- proof that Angel is, indeed, the only one who remembers their tender reunion.
