After when Kat erased Harley, Lone, Fiona, and Millie's of Kat being an alien and destroyed the machine he did with. Coop made a remember gun to zap them and restore the memory of Kat being an alien and hid it and the blueprints where he knew kat could wouldn't find it. When Coop and Dennis were hanging out with Lone, Fiona, Harley, and Millie, he zapped Lone, Fiona, Harley, and Millie. They all 4 said they remembered about Kat being an alien. Coop said Kat erased your memory about him being an alien and I just gave you those memories back. Millie went and got Kat and told him tell daddy your an alien. Kat was shocked she remembered. Mille said Coop told us you erased our memories and then he gave us them back. Millie told Kat not to do that again or she send him back to the alien planet. Kat showed Coop and Millie's dad (Burt) that he was an alien. Burt said he was sorry to Coop for not believing him and they hugged. Harley and Lone volunteered to help Coop with Kat. Millie told Coop she had Kat tell their dad about him being an alien since she wanted their dad to believe Coop and not think Coop was telling lies or making up stories. Coop told he thank you and they hugged. Kat walked up to Coop and hugged him showing he was sorry. Coop and Kat shook hands which meant that they were friends They all started playing soccer. Dennis brought Fiona to Coop since he knew they had a crush on each other and congratulated Coop about saving the world from the Kat Aliens and restoring their friends memories. Fiona said to Coop my hero. Coop and Fiona kissed. Coop said to all of them I'm glad you all believe me now and I'm glad me and Kat or friends now. They all said of course and will in any way we can. Kat showed him he will help too by spying on the Kat Aliens. And they did a group hug.
