Thoughts on Batman: City of Owls...

Spoilers
So…like…
they want us to believe Bruce has a brother and they want us to be alright with how Alfred (nor Bruce) never brought it up until now…? They try to explain it and make it feel like it makes sense but it just doesn’t sit right with me.

Everyone seems to be ok with this?..am i the only one who feels its weird and kinda plot hole like for this to be cannon,? …it just feels jarring and awkward for this to just fall on to our laps outta nowhere idk, whats your thoughts
