The new 'The Last Jedi' trailer may give away a major spoiler

The new trailer for "Star Wars: The Last Jedi" went online Monday night, and it didn't disappoint.

Luke teaching Rey the ways of the force! Porgs! But the biggest moment is Kylo Ren flying his ship towards what looks to be the command ship General Leia is in ... and about to fire on it. Did we just get a major spoiler? (Hope not.)

A new poster for the movie was also revealed Monday.

Here it is:
