"I'm getting a strong energy core signal! It's somewhere in this area!"

"An equipper! Use it to prepare yourself!"

"That's a data point! Let's smash and grab!"

"Collecting data points will release the locks."

"I think you can climb up there!"

"That's the energy core! But it's locked..."

"Whoa - they're climbing! They're higher up than Agent 8!"

"Looks like you could get in there using the Inkrail!"

"Fifth lock released! Three to go!"

"Seventh lock released! Just one left!"

"All locks released! The energy core..."

"Follow it, Agent 8!"

"Agent 8? AGENT 8?!"

Trivia

 * The developers revealed that if Agent 8 gets splatted during this phase, they will actually die, because they are not connected to a respawn platform. This means the game goes back in time every time you get splatted during the escapes.
