The Courtwater's palace is infiltrated while Regina and Oliver are off fighting the war or in diplomatic talks by wizards from the opposing kingdom looking to use Lucas for their cause. It had already been planned to secretly get Lucas out of the country to safety with one of their allies, and in the chaos Lucas gets out of the city and starts heading for the border. Meanwhile the attack in the palace in crushed and control regained, and while soldier go in search of Lucas to make sure he's safe the palace keep fact of the attack and that Lucas isn't there anymore from getting out to the public, though of course there are rumors.
So there is Lucas trekking through the countryside toward the border in the mountains when everything just starts steadily getting bad. He's spotted a few stray enemy wizards flying by overhead, it's getting darker and foggier, and this part of the country is notoriously dangerous anyway what with the witches and beasts said to wander these parts. Which is when the moving castle comes shuffling along and ends up kind of inviting him in (probably no fire demon but still going with that part of Jerry's soul is running this thing so of course it would invite Lucas inside), and between the fact that the wizard of this castle is only known in rumors and ghost stories for devouring women's hearts and that the castle gives him oddly safe and protective vibes, Lucas goes inside for the night.
There's no one around but it's warm, and Lucas waits around for a bit wondering if someone will show up, before just dozing off on the couch. Jerry comes back during the night to find Lucas sound asleep, and so of course it's an initial shock but with Lucas sleeping there's some time to get his composure and realize Lucas never has to know it was him. He can just go up into the castle, magic Lucas some breakfast or something, and send him on his way and that will be fine.
Only his nerves are still going and he ends up accidentally waking Lucas while he's preparing breakfast. It's that awkward, shocked moment of them being face-to-face, the really halted conversation of "It's you," "Yeah," etc with Lucas steadily getting internally worked up because omlit'sJerrysomanyquestionsomlJerry before Jerry is quick to, with some hesitance that Lucas at least can pick up on, quickly begin the process of sending Lucas on his way. A notion that Lucas wants to argue with until it dawns on him - the enemy is looking for him, and if he stays, he'll lead all that trouble right to Jerry.
So, Lucas lets Jerry send him off. Jerry gives him some food and some stuff to help him on his travels, and as he's heading out the door Lucas looks back up at him and tells him something to the effect of wanting to see him again sometime later. Jerry's still in that mindset of 'no just let me be alone go back to your perfect life' so he gives some kind of half-response and tells him goodbye. And it's just that moment of Lucas standing on the mountain path as the sun comes up, watching the castle move on, almost about to cry because Jerry was right there and he just walked away - let Jerry think that he was happy with just walking away. His best friend that he had been hoping to see again all these years and just in a blink of an eye they were apart again. But in the end he just makes this silent promise to find Jerry after the war is over and he turns to continue on to the border.
Pan back to Jerry, still dealing with seeing Lucas again, and starting to realize the implications of Lucas being out on his own with the war (which Jerry has just been trying to stay out of and so hasn't been following much) going on. And it doesn't take him long to do some checking around in the city and hear the rumors about the attack on the palace and the prince maybe or maybe not escaping. Now believing that Lucas is probably in grave danger, he flies back toward the mountains to search for him and make sure he's fine.
Lucas meanwhile is not fine, he's been discovered by enemy wizards and has been trying to evade them as he races toward the border, but he's running out of plans and they're closing in on him. He's already been knocked around quite a bit and ducks into a small cave to hide and try to catch his breath. But the wizards locate him, and Lucas is just pressed in the back of the cave praying as he sees them approaching the opening.
And it's that moment that the wizards get blown back away from the cave, and rather than caving in, stone around the cave lift up and form a wall over the entrance and Lucas can soon hear a battle going on outside. Jerry taking out all the enemy wizards and magically cleaning up the scene before finally going over to dismiss the wall over the cave opening and get Lucas. Cue more proper reunion starting with Lucas thanking Jerry and apologizing for leaving him but he didn't want to lead the enemy forces to him and feeeeels.
