out that Regina was responsible for threatening him. Emma accuses Regina of threatening Archie, but Regina says that Henry is missing again. Archie conjectures that Henry may have gone back to the mine shaft. There, Henry begins to investigate the area and comes across a glass item similar to the one Regina found earlier that he puts into his backpack. Archie goes in to search for Henry and finds the boy, but as they try to escape, an aftershock blocks off the main entrance, leaving an injured Archie and Henry trapped. They find an elevator shaft, not knowing that above ground Emma and Regina have taken the suggestion of blasting the main entrance from Marco (Tony Amendola), which results in the elevator carrying Henry and Archie being lowered even further after the blast takes place. Inside the elevator, Henry asks Archie why he refuses to believe that he is Jiminy Cricket. Archie acknowledges that he might share Jiminy's personality and in a similar fashion to his alternative past, yearn to be free from being told what to do. Meanwhile, above ground, Emma finds the opening of the elevator shaft and volunteers to go down the shaft, where she succeeds in rescuing Henry and Archie. Archie tells Regina that he will continue to see Henry and that if she attempts to interfere he will take action against Regina and have her declared an unfit mother. Regina backs down after Archie's threat, she looks at the object she had in her pocket and throws it down the shaft, where it is revealed that it is a small shard of the infamous glass coffin of Snow White's (Ginnifer Goodwin). Concurrent with these events, Mary Margaret (Goodwin) continues to visit the amnesiac David (Joshua Dallas) at the hospital. At the same time, Kathryn (Anastasia Griffith) also continues to visit David, showing him pictures to jog his memory but later admits to Mary Margaret that he doesn't remember anything that he saw in the pictures, although he claimed otherwise when talking with Kathryn. As Mary Margaret notices David becoming more attracted to her, she still feels threatened by Kathryn's presence. This prompts Mary Margaret to submit her letter of resignation as a volunteer at the hospital.
