Raven left Luna resting in their private chambers.
He also informed their daughter that Luna's out of her seclusion and is now resting. He knows that Vanessa missed her mom these days so he made sure to tell her how she's doing.
As for the rest of the team, they're resting too. But for Raven himself, he wasn't done, not yet. He probably won't be for long time.
He returned back to the throne room but instead of restarting with his research, he just closed his eyes and got immersed on his own thoughts.
Don't get him wrong, he was glad that his wife and friends broke through and held enough power to protect themselves. However, due to some reasons, he couldn't bring himself to feel genuinely happy for them.
This goes especially well for Mark and Luna.
Mark sacrificed his and his wife's future chance of having another child just to do his part at the upcoming war.
Luna was chosen to be the host of a budding Divine Realm.
