Unreliable Narrator.
Plus it's a huge evolution from Joel referring to Ellie as cargo in episode 3, to calling her what he used to call his daughter in this episode.How many times did you hear Ellie referred to as “the girl” over and over again in that episode and also that she could never possibly survive all alone without her friend … a man … by her side
That was an amazing line you mention … amazing job of framing by the writers the entire episode … after all ellie had been through, it seemed like she didnt need to hear it … that she was so strong that she was the polar opposite of a baby girl … but in the end she did need to hear it.
