Rescue, not necessarily. However **SPOILER ALERT (sort of)** during the assault on Tony's mansion, Tony has his Mark 42 armor (the one featured in all of the trailers) form up around Pepper. This can be seen in one of the TV spots: https://www.facebook.com/photo.php?v=10151508933187290. After Pepper is safe, Tony calls the armor back to himself.
