The 39 Clues/Heartwarming


 * Every book has one!

Series 1: The 39 Clues

 * In Beyond the Grave Amy and Dan have one really horrible fight over Grace and her memory. Amy begins to think that Grace didn't really care about them and was just using them all those years. Later on, Amy and Dan remember a time they went to a history museum in New York with their grandmother and they all ate pretzels on the stairs. Grace tells them that the museum was nice but this is the best part. The Fridge Brilliance of that is, when Grace says she likes spending time with them more than the museum, she also means her travels and adventures all over the world too (which they didn't know at the time)
 * Dan getting another picture of his parents after he lost the only picture he had of them in Paris.
 * Irina Spasky talking about her  and then
 * In book 9, Storm Warning, Amy and Natalie's short conversation, which doubles as a Tear Jerker.
 * Jonah's dad in the last book when
 * Whenever Amy or Dan run into a relative of their parents, Shep,, Amy will see her dad and brother's facial expressions in Dan. Their uncle Shep reminded them so much of their father.
 * The last book has many of these,.

Series 2: Cahills vs. Vespers

 * In the second series, Evan and Amy's interactions are this a good deal of the time (though as usual when dealing with Shipping, YMMV)
