Batman's mom?

I can't remember the exact line, but it was about parenting and feeling like Thomas Wayne (Bruce Waynes Dad) and/or like Batman's Mom "whose name I can't remember." And looks at the camera (an obvious jab at the Martha line from Batman V Superman. The joke being her name is so famous now for what some think is a dumb reason and he pretends not to know it).

Because in Batman V Superman the only 'reason' that Batman didn't want to kill Superman(or vice versa cant even be bothered to recall it now) was cos their mums were both called Martha!!(roll eyes)
