The 3-Liner would get shuffled. This is (or at least was, before the new rules) a really common play for people to use. Other possible scenarios are that, if the 3-Liner is rescued and later Falls Away, it still has one rescue on it, however, it doesn't count towards anyone's score. Also, it can Buried either before or after it's been rescued. All of this applies to the 2-Liner as well.
