Diaval had seen everything that at the castle of Asgard after the death of Silena and her baby. The funeral, the wedding, and those times he wasn't in Asgard, Diaval was with Loki as best as he could to try and help him through his dark times. He didn't feel the same deep saddened feelings for the loss of their favorite queen but he knew what Loki was going through. For when the funeral came, he picked a budding rose that had yet to fully grow and gave it to Loki. He saw it fit as a reminder of Silena and how she grew with Loki around her. As much as it was a saddening gesture, that was just how Diaval saw it and hoped that Loki wouldn't be so sad, having a feeling that Silena would always be with them. In their hearts.

When of the Death of the King came, Diaval had to warn Loki, feeling something much worse was going to happen. flying as fast as his wings could take him. This wasn't going to fair well at all. 

Arriving to the Moors, Diaval flew to Loki and swooped low as he transformed, running as he had done so and called out. "Loki! Loki I have bad news! The King was killed by the woman he married. I saw a huge army, one that has probably already taken Asgard!" He had to catch his breath a moment before he could continue. "I think the Moors maybe next."
