Picture
Daphne
The photo in Daphne's hand was of Puck and Sabrina. Not together, of course not, they "hated" each other. No, it was from the fourth of July and they were actually both talking to someone. A boring great aunt, if Daphne's memory was correct. But they were both glancing at each other and laughing. You would only know why if you looked closely and noticed the garden hose slowly inching its way towards the great aunt. Daphne still doesn't know how they managed to do that, and she doesn't really care. That's not why she likes the photo; she likes it because it is prove that on some level they like each other.
Granny Relda
When you look at a photo, often it's not the entire story. Take the picture of Sabrina and Puck at the Fourth of July. If you were a stranger looking at the picture, they would think they were the best of friends sharing a laugh at a privet joke. If you were an observant stranger then you would notice the garden hose and believe that they were mere strangers sharing a laugh at the funny position of the hose. If you were a Grimm, then you would realize they were probley looking at each other to make sure that the hose wasn't coming at them, and then, when realizing it wasn't, laughing.
