I feel like people forget Bruce Wayne canonically has two siblings, he has an older sister named Samantha Wayne and an older(?) brother named Thomas Wayne JR though only in certain universes
In the live-action series pennyworth is where he has the sister Samantha and Thomas I couldn’t find the exact origins but he is there and has been showed a few times
I feel like Dick, Jason, Tim, Damian, and the bat family aside from Alfred would be so confused when all of a sudden there’s a random lady and a random man in their kitchen and for some reason their dad is CRYING because he hasn’t seen his siblings in years and Samantha and Tom are so quick to just reacting with “oh fuck” and telling Bruce not to tell Alfred that they snuck in and to “stop fucking crying don’t get us in trouble baby bat”
That’s when the others realized Bruce was the first baby bat and not Damian
