Back at the lair, Mikey was skateboarding on the halfpipe. Casey was playing one of the arcade games. Ellie was skating around the lair on her skates. Leo, Lee, Donnie, Donna, and April were standing over the table as they were trying to figure out the Mayan connection between the monsters and Mr. Winters.
"So, what are we looking for?" April asked.
"Well, according to these star charts, the portal is set to open directly over Winters Tower in the next 24 hours." Donnie explained.
"So the legend is right. Three thousand years." April said.
"And when the portal opens, we'll lose the city to monsters within hours." Donna said, showing the map of the possible outcome on the visual screen. "Within days, the country. And within weeks, the world."
Mikey used his right hand to balance himself in a handstand on the deck of the halfpipe.
"Oh, so it's like Halley's comet, only monsters come out?" Mikey said.
"Yes. I guess so." Donnie responded with a slightly surprised face.
"I'm smart." Mikey said with a chuckle.
Mikey went back down the halfpipe on his skateboard only for him to crash painfully.
"I'm okay." Mikey groaned in pain.
"I'm coming, Mikey." Ellie said as she quickly skated over to her mutant boyfriend.
"Why do we need Raph, anyway?" Leo asked angrily. He got up from the chair and walked away from the table. "It's his temper that always jeopardizes all our missions."
"Okay, Leo. Whatever you say. Nobody was talking about him." Donnie mumbled as he looked at the shrugging April and Donna.
Lee stared at Leo with a worry face and got up to follow him. Leo started to walk up the stairs until Splinter stopped him for a moment just when Lee stood few inches behind to the mutant rat.
"Leonardo, this team you are so eager to lead is incomplete. You know what you must do." Splinter said.
"Yes, sensei." Leo said with a sigh.
Leo exited the lair to find Raph, leaving Lee walk up to Splinter.
"I know, you're trying to solve your sister's problem, but this is something you two need to fix yourselves." Splinter said to Lee.
"Splinter, I know Ella likes to take things into her hands." Lee said. "But I just know that something's wrong with her. She kept saying she doesn't remember what happened, but I know something's up when I felt her aura. It was almost...dark."
"I know your concern for your sister, Leona." Splinter explained, placing his comforting hand over Lee's shoulder. "You can help her, but this is something she has to handle on her own. She can battle her inner demons. All she needs is time."
Leona nodded her head and exited the lair to find Ella.
At Winter's Corp, three generals were trapping the eleventh monster in a cylinder cage until the door opened behind them.
"Generals, I think our brother has plans to betray us." Aguila said dangerously. "The 13th monster must not be found."
