Vault Hunters commenting on each other’s action skills?

So in the Pre-Sequel the vault hunters would comment on each other’s action skills a lot. I mained Claptrap and the reactions to my action skill were hilarious.

In BL3 I did my first playthrough as FL4K co-op with a friend playing Zane and I just kinda assumed this wasn’t a thing. Then I played co-op with an Amara and she phasegrasped something and my FL4K was like “Thank you, Amara!” and I was like wtf. Now I’m just kinda sad because I’m really curious what FL4K and Zane would have to say to each other but for some reason this doesn’t seem to be a thing? Has anybody heard any unique dialogue between them? Can’t tell if this is bugged or what.
