After freeing Talia from her father's clutches, Batman engages Ra's Al Ghul in bat-tie, holding him at bay long enough for the maddening effects of the Lazarus Pit to wear off. Whereupon Ra's activates a self-destruct mechanism in his mountain lair and beats a hasty retreat with Talia, leaving Batman and Robin to be finished off by a cave-in. The pair escapes in time and narrowly avoids being buried alive in an avalanche, giving Ra's more than enough time to vanish.
