Wonder Family

Clark, Diana and Lara

So I will set the scene of this pic. Diana had been under pressure (Cadmus) after she find out she was pregnant and retreated to Themyscira.
The last three months of the pregnancy Clark was sent off world to deal with a conflict.
He returned to Earth a month and a half after the birth and Diana is introducing him to Lara for the first time.
This is why Lara is looking up at Clark with wonder.
So I like to think of it like a lioness introducing the cub to the father.
