[In 2018, The pager is seen with the Captain Marvel symbol. Seconds later, the pager turns off. In another room, The Avengers are dealing with the consequences of the failed counterattack against Thanos that lead to the decimation process as they return to the New Avengers Headquarters. On the computer, the numbers continues to rise as the global death toll reaches 3.2 billion.]

Steve Rogers: This is a nightmare.

Natasha Romanoff: I've had better nightmares.

Daniella Jones: I've had worse.

Natasha Romanoff: Sorry.

Daniella Jones: It's fine. Gotta move on somehow.

[James Rhodes walks in]

James Rhodes (Rhodey): Hey. So that thing just stopped doing whatever the hell it was doing.

[Rhodes, Romanoff, Jones, and Rogers head to the chamber housing the transmitter device, where Bruce Banner is analyzing it.]

Natasha Romanoff: What have we got?

Bruce Banner: Whatever the signal is sending, it finally creeped off.

Steve Rogers: I thought we bypassed the battery.

Daniella Jones: We did.

Rhodey: It's still plugged in, it just... it just stopped.

Steve Rogers: Reboot and send the signal again.

Bruce Banner: We don't even know what this is.

Natasha Romanoff: Furry did. Just do it, please. You tell me the second you get a signal. I want to know who's on the other end of that thing.

[As Romanoff turns around, she finds herself face to face with Carol Danvers.]

Carol Danvers: Where's Furry?

[Cut to black.]
