I Won't Forget It

Bib Fortuna plots against Jabba, but ends up saving his life:

"I never imagined how loyal you are, Bib. I thought that you were...waiting for your opportunity.  I mistrusted you."
 "I...You...Uh."

"You killed like a champion for me.  You risked your life.  I won't forget it."

Notes:
Spanish makes the past progressive in the same way as English: Yo estaba mirando - I was watching.
Esperar is more accurately translated as to await, since no preposition is necessary.  Te espero - I await you.
