The rest of the team heads for the cavern, as Data and Picard detour to Guinan's home. As Clemens, tipped off by his reporter friend as to Data's involvement with the team at the hospital, heads for the cavern, the team arrives there. Assuming the cavern on Devidia Two is similarly designed, destroying that cavern should stop the aliens' presence on Earth. They decide to attempt to use the ophidian to head back to their century, but are stopped by the sudden arrival of Clemens, who threatens them all with his gun and demands they leave with him. Just at that time, however, the aliens phase back in and attempt to recover their cane.
Data grabs it back and subdues the man, only to have the cane flare twice.
The first flare seriously injures the female alien, and the second blows off Data's head and blows everyone else to the ground. When they revive, they see the cane vanish and a time-gate open. Just as the gate closes, however, Clemens revives and also follows through. Back on Devidia Two, everyone seems all right, but Riker harshly upbraids Clemens for following. There, Geordi begins attempting to reattach the head they currently have, while Troi volunteers herself as Clemens's escort.
