The new Avengers: Endgame trailer is here and it’s packed with emotion. Recapping half of the MCU movies to date, charting the rise of our heroes and the devastation left by the Thanos snap, the remaining members of the team are grief stricken and broken but determined to do “whatever it takes” to defeat Thanos.

Clint Barton aka Hawkeye (Jeremy Renner) was conspicuously absent from Avengers: Infinity War (we’re told he’s under house arrest) but we know he survived the snap and will be back for Avengers: Endgame in his new guise as Ronin (more on that later).

But one of the highlights of the new footage is a glimpse of Barton training a young woman in archery. This could possibly be his daughter Lila who appeared briefly as a young child in Avengers: Age Of Ultron, although we think Lila would be too young.

Instead there’s another option for who this young woman is and she could be a key part of the MCU.
