Narrative jumps between her two times back and forth. The story is wähend "The Last of Us" and tells the action-packed part.
The second part tells Ellis story before. This part is about two teenagers as they think and feel. Emotional really very touching.
A word to the 15: Yeah, that's not really cheap. However, we Naugthy Dog tells a story to the highest level. For me personally, the alternation between action and beautifully narrated story about the relationship between two people liked it very very well.
