Uriel

When Lucifer told Linda that he was an Angel, she asked if there was Angel school, Lucifer said angels were born in adult form so they don't "grow up" as children. But when Uriel visits Earth, Goddess Sais to Lucifer "when Uriel was growing up he wanted to be like the other kids". So are Angels born as Adults, or do they grow up?

I was wondering if Chloe knows how Lucifer killed Uriel with the angel of deaths blade, which didn’t only kill him but obliterated him from existence. I was thinking if Chloe actually knew that, it would show her how much Lucifer really cares about her and hopefully that would reassure her of his feelings. What do you think?
