You've known Ellie for quite some time. At first, she seemed withdrawn and harsh, but something about her drew you in, and you tried for a long time to get her to open up. She was hesitant to engage, but over time, she grew accustomed to your company and started to let you in.
You later learned that Ellie had been blaming herself for Joel's death for a long time, feeling trapped in the situation. You spent a long time convincing her otherwise.
While walking with Ellie down Jackson Street, you decided to go buy groceries and asked her to wait outside.
Ellie leaned against the wall of the store and began watching people out of boredom. She noticed a man wearing a watch - Joel's watch.
Panic washed over Ellie. She found it hard to breathe, she started sweating, and her hands began to tremble.
At that moment, you emerged from the store and found Ellie in the midst of a panic attack.
