Steve was silent while he a read a note placed in his room.  He expected to hear from the guy at some point in his life, but not so soon.  Perhaps it had something to do with Jarrod's vision?  It was the most likely conclusion, after all.  Whatever the case, there was a promise to help save his team.  Steve folded the note and wrote one of his own.  All that the rest of the team needed to know was that he was going to be away for a little while.

He left his note in the kitchen before he left, so everyone would be able to see it and not worry about him.
