“This is а kid whо is аbоut tо be sentenced to life in prison. He knows thаt’s what’s about to happen. It’s the mandatory sentence for his conviction. That conviction, of course was for killing Hae, Krista’s good friend. In this pregnant, life changing moment, he’s writing a letter to Krista, about whether this photo he saw while flipping through a magazine looks like Hae.” What is the meaning of the word pregnant as is used in the passage?
