The next day at Bueno Nacho, Kim and Monique talked about what they did last night, and Monique is too excited to tell Kim what had happened to her last night.

"So Monique how was the movies last night?" said Kim

"Great Kim best night ever!" said Monique

"It was that great, huh, what movie did you see?"

"It wasn't the movie that made my night Kim, but it was someone I meet,"

"Really, wow, so who was this person last night?"

"He's a cute and a total sweetheart I met him a few days ago we chatted for a bit until he had to go and last night I met him again ask him if he wants to go with the movies with me and he says yes,"

"And what happens after the movie?"

"Well we talk again, and I gave him my phone number, and he gave me his,"

"I'm glad that you meet someone that isn't a total jerk Monique,"

"Yeah, I can't wait to see him again,"

"So who he is, Monique? I would love to meet him,"

"His name is..." before Monique could tell Kim the boy name Kimmunicator started to buzz, and Kim pulls it out.

"What is it Wade?" said Kim

"Kim there was a break-in in the Field museum stolen a priceless gem," said Wade

"Any leads on who could've taken the gem?"

"No, but you wouldn't believe what the thief did to the museum when you see it for yourself,"

"Alright Wade I'll go get Ron, and we'll go to the museum," Kim hangs up and looked, Monique "I gotta go Monique tell me more about this guy your interested in when I get back,"

"Go get that thief girl," Kim left the Bueno nachos as Monique pulled out her phone and started to text the boy she liked.

Kim and Ron arrive at Chicago Field Museum, seeing the thief down to the museum as they see Ice covering parts of the Musume from the roof to the staircase has ice stuck onto and slowly melting away.

"Woah, the thief did a real number on the museum," said Ron

"You say it, Ron, there so much Ice around the museum," said Kim.

"Did you think the thief had some sort of ice weapon that they used to break in?"

"Either that or something else to get in and steal a gem that museum had let's go in and meet with the lead detective,"

Kim and Ron walked into the museum seeing their even more ice inside the museum; two cops were trying to warm up two frozen museum guards. The two teens meet up with the lead detective, who was looking at a broken display case.

"Detective Louis," said Kim

The detective turns to Kim and Ron "Kim Possible glad you're here because this case isn't what I usually take on,"

"Detective, do you know what gem the thief stole?"

"Yeah, the thief stole the Royal Sapphire that is worth about 1.5 billion and suppose to be open to the public today,"

"And how did the thief break into the museum?" said Ron

"The thief started to freeze parts of the museum then the thief froze the guards smash and grab the gem and escape in a black sports car,"

"Maybe the security camera has the footage of thief," said Kim

"I'll let you two check it out while go check on the museum guards,"

Kim and Ron go to the security room to see the security cameras to see the thief freezing some of the cameras so it wouldn't show their faces. But luckily, one of the cameras wasn't affected by the ice Kim, and Ron got a look at the thief to find that she looked more alien than human; she had pale blue skin and ice for hairs.

"I think we need Ben, Gwen, and Kevin help on this," said Kim

"Yeah K.P. still we're seeing an alien but why is she steal the gem?" said Ron

"Don't know she stole it for someone else or herself maybe those three can tell us,"

Kim and Ron return to Middleton they went to Team 10 hotel room where they got to the trio room they see Ben texting someone.

"So what you guys got for us?" said Gwen

"Well we were looking at a break-in at a museum with a thief stealing a priceless gem, and the thief looked more alien,"

"Wait, did the thief use ice to break into the museum?"

"Yes," said Ron

Kevin took one of the escaped criminal alien files, and he found the picture of first escape alien Liana "did the thief look like her?" Kevin shows the image of Liana to Kim and Ron

"Yeah, thief looked exactly like her,"

"She's one of the aliens that escape from the null void," said Gwen and that made Ben stop texting and joins in

"What did she take?" said Ben

"The Royal Sapphire but why she took it?" said Kim

"She probably trying to sell it off to buyers on other planets to pay a lot more for the gem," said Kevin

"And where could she be now?"

"I got no idea," said Ben

"Me neither," said Gwen

"I know where she could be," said Kevin making everyone turn to him
