In the issue's 'epilogue' we get to witness a soft moment between the father and son team which was a surprise seeing that the last few issues were all-out action issues.
Awww man this totally made me shed a tear. It's been a while since we saw a Batman that's emotional and a Damien that's vulnerable to his emotions.
Also note that the pearl that Damian shows Bruce is actually the pearl that belonged to Bruce's mother. Damian has been searching for those pearls since the beginning of the new volume. This adds more drama to this already dramatic scene.
