>>103323852From what I understand he called the Solar draining Xenomorph things to get Clark (who is essentially a solar battery) off from building the moon and tried to convince him to give it up by telling him stuff like "We can get a better moon/We can make a better base/etc...." because he's being his dour prep time pessimist self and sees no reason to build the same moon again.
Clark pretty much figured out Bruce called those things to get him off from building the moon base again, so he didn't budge or listened to any of Bruce's warnings and just kept doing his thing.
Clark gives him an uplifting speech, tells him he knew about Bruce calling those things and pretty calls Bruce's bluff about those things being dangerous when he goes "Yeah you made them harmless and I'm going to be fine, right Bruce?" to which Bruce respond by just griting his teeth and pushing the button to call off the Mega Xenomorph just when it's about to get to Clark.
Clark was the one who wanted to lift Bruce and everyone's spirits up, Bruce was just being all Batman about it.
