The only reason I didn’t mind Jason’s display in Event Leviathan is because he fought them primarily one on one & he was fighting to escape the entire time. I can buy he’s a capable enough fighter to do that but had he utterly crushed all of them (individually or all at once) that would’ve been a different story.
With Dick currently off the table, I’m kind of disappointed they didn’t take the opportunity to further develop Damian’s relationship with the Batfam. Would’ve been a perfect time to do so but the most we got was one undercooked subplot that didn’t go anywhere.
