У них хотя бы в ранобе был диалог?

не совсем у них - был диалог у Чёрной Ханекавы и Шинобу в спальне Арарги. хз, считается ли. вот немного подробней с англ. вики (лень переводить, честно): 
 
Tsubasa Tiger 
This section contains content from Nekomonogatari. 
 
Black Hanekawa finds Shinobu in Koyomi's room after she disappeared in Shinobu Time. The two come to an agreement to help each other, and arrive at the now burned down Eikou Cram School. Off screen, they end up fighting a monkey-crab oddity together when Yotsugi comes to finish the fight with Unlimited Rulebook. She then stays at Namishiro Park until Koyomi and Suruga Kanbaru find her in Shinobu Mail.
