I couldn't get the implication or metaphor of the phrase in the following sentence; is it a slang?
The context is :
Bruce Banner, the Hulk, got under the mind control of Wanda, and he went rogue, causing great damage to the civilians. The whole team is a mess now.
Here is the sentence:
He was talking to Maria Hill, who was on the dashboard screen. “The news is loving you guys,” she said. “Nobody else is. There’s been no official call for Banner’s arrest, but it’s in the air.”
“The Stark Relief Foundation—” Tony began, but she was ahead of him.
“Already on the scene. How’s the team?”
“Everyone’s . . .” Tony had meant to say something reassuring, but he couldn’t make it happen. “We took a hit. We’ll shake it off.”
“People find out the Avengers got carried off the field, there’s going to be panic,” Hill said. “And that’s from the people that like you.”
“Recommendation,” Tony said.
“Stay in stealth mode and stay away from here.”
“So run and hide.”
“Until we can find Ultron,” Hill said, “I don’t have a lot else to offer.”
