As Shining Armor and Daxter were both supremely confident in Jak's ability to win the race, they felt no need to stick around to see its outcome. Instead, they decided to head back to the Underground HQ, to see if they could do anything else towards freeing Haven City...only to find there was nothing that needed to be done. The Baron had greatly diminished his military activity within the city, for some reason.(1) Samos did have a task for them unrelated to the Baron's activities, however.
"There's something I left behind long ago in my hut," he'd explained simply. "It's time to retrieve it...oh, and clean the place up while you're at it!"
Shining wasn't about to refuse, as he was certain he could handle making his way through Dead Town to Samos' old hut with Daxter's help. When he got there, however, he discovered Keira had left him something - probably via Ashelin - to help him get through himself. The large, yellow and gray exosuit was designed to be operated by a human, Keira had included a modification to enable Shining Armor to operate it physically, without relying on his still somewhat limited magic.
Shining found it rather refreshing to crash around in the aptly named Titan Suit. Having been the tiny one his entire life - at least until Daxter's transformation - it was rather enjoyable to be stomping around as a giant and smashing everything he came across. It also included an input jack for his horn, letting him inject a very small amount of his magic into the suit to electrify the exterior to keep Metal Heads from holding on. He made sure to only do it in short bursts, to keep the Dark Eco in his blood from reacting too strongly. The jetpack on the Titan Suit's back made jumping a great deal more fun than it had ever been before.
Shining admitted privately to himself that he wasted a bit of time leaping around like crazy, just for the thrill of it. He didn't see the real harm, as they weren't on that much of a schedule. Besides, he was able to wield his Peacemaker outside the Titan Suit to take down the larger Metalheads with heavy guns before ever getting in their range, making the trek both easier and safer.
Once making it to the hut itself, they found a glowing green seed near the peak of the hut. "Good work, Shining Armor!" Samos proclaimed through the communicator as Shining retrieved the seed. "Oh, and Daxter, I suppose." His voice turned more serious as he began to explain what it was. "Before we came through the rift long ago, I was nurturing that Life Seed from the Great Tree. It seems the Metalheads are...attracted to its power. Take the seed to Onin. She will prepare it for Samos."
"You mean...you?" Daxter asked, confused.
"I think he means the younger him," Shining clarified.
"Exactly!" Samos confirmed. "He needs the seed's power to become...sagely."
"Let me get this straight," Daxter began. "It's fair to say that by bringing your younger self the Life Seed now, we helped you become the sage you are today. We helped you get your powers in the first place! And you never thanked us?"
"I all but raised all three of you," Samos countered.
Daxter hesitated. "...fair enough," he allowed as Shining snickered.
"Now go do it!" Samos ordered. "Jak's going to meet you at Onin's hut. He had...a bit of a problem with Erol while you were gone. Something about refusing to throw the Class 1 race for profit and racing through the city, and now Erol wants to kill him in the final race."
"I look forward to when Keira divests that idiot of his reproductive organs," Shining grumbled as he stored the Seed away.
It didn't take Onin long to properly energize the Life Seed so The Shadow would be able to use it to awaken his powers as a sage. Shining had the foresight to hand the Seed off to Jak and let him bringing in, preventing yet another conflict between Daxter and Pecker. With the energized Life Seed in hand, Jak led the way to Haven Forest to meet up with The Shadow.
They found The Shadow waiting for them in the center of a peaceful glade deep within the forest, at the foot of the largest tree. He looked...peaceful.
"You told us you needed the Life Seed," Jak began, before realizing how weird that sounded. "Uh...sorta, I mean-"
"Just give him the Life Seed," Shining chided teasingly. "If anyone here understands, he does."
"Yes," The Shadow agreed. "As confusing as it is, I do understand what needs to be done." He took hold of the Life Seed. "It will help me speak to the plants-"
At that moment, several Crimson Guardsmen in jetpacks dove in, from the sound of their shouts under orders from Erol rather than the Baron. Shining and Jak both pulled out their weapons. Before The Shadow could say anything, they'd stared shooting the group of Guardsmen out of the sky.
The attacking group wasn't that large(2), and it didn't take long to deal with them. With that done, Samos achieved his Sage abilities unmolested. The plants told him of a grave danger...that had already been averted. He found that oddly peculiar, but Jak merely glanced away with a smirk.
(1) In the game, this would be where you'd have the mission to destroy the Blast Bots...but here, the Baron's now on Jak's side.
(2) Erol doesn't have the same pull the Baron would have here, after all.
