The boxes and dust in the house were something you expected to happen when you agreed to help her move (since Helena, Zinda and Barbara were very far from here, at least for today). Dinah needed a new life after everything that happened with Sin.
Nostalgia was something that, although you both knew it was going to happen, was not going to be as beautiful as other times, because this time it carried some pain.
"I still remember that day" she grabbed the photo frame, everyone looked happy at that moment, even Helena seemed as happy as Zinda. Although your back was to Dinah, you could see the glow of her smile from afar. "Probably the calmest day among the four of us, and that's very difficult." She let out a small smile, which lightened the atmosphere a little.
Perhaps, the Birds of Prey were the pillar that kept Dinah's feet on the ground all this time, her reason for waking up another day wanting to kick ass and make the ears bleed of those who made the city a worse place.
"I'll be away for a long time and... I'm afraid that something between them will go wrong" despite the nostalgia that hit him from seeing that photo, a hint of worry was noticeable in her voice.
