Thor : (To Fury) Your work with the Tesseract is what drew Loki to it, and his allies. It is the signal to all the realms that the earth is ready for a higher form of war.
STEVE : A higher form?!
What does "a higher form of war" mean? Could you explain for understanding?
STEVE : I’m sure if he still made weapons, Stark would be neck-deep...
TONY : Wait-Wait! Hold on! How is this now about me?
STEVE : I'm sorry, isn't everything?
Please try and guess Steve's uncompleted line and complete sentence. "Stark would be neck-deep in big trouble" or "Stark would be neck-deep a bundle of paper money (Stark buried in the money)". Which one do you think makes sense?
And Steve said "isn't everything?" What does that mean?
