All of the things at the diner had just happened, resulting in you being in stage halfway between shock and grief. Between Joel getting injured, you having to take care of him, what David tried to do, and killing him – you're mentally and physically drained. It feels like your body is about to collapse at any second now. You've been running on nothing but fear and adrenaline for the past couple of months and your body is finally about to give up.
You and Joel are on your way back home, or the closest thing you have to one of them currently. You're on your way back to the house whose basement you've been taking care of Joel in for weeks now. Despite his injuries, he really came all this way just for you. It's dead silent between the both of you. The only sounds to be heard in the forest are Joel's heavy breathing and the sound of snow crunching under your feet.
