Uncle Kalen
His uncle was clearly in great shape and had even managed to put on some weight, suggesting that his stay on the B842 was tantamount to a holiday. Jake only needed a glance to figure out that Kalen hadn't participated in any Ordeal yet.
His aura was normal, as were his movements. An Evolver had something different in his gaze and the increased stats were passively manifested by a stronger and slower beating heart, a lighter step and a propensity to speak very fast. The last phenomenon was due to the increase in Agility and Intelligence which gave a slower perception of time.
Even Jake still had the greatest difficulty controlling his speech rate when talking to normal people. Luckily, the people he was associating with these days were all Evolvers who had maximized their Agility, with the possible exception of Will.
That was in the past, though, since after selling the carcass of the Rank 7 Digestor, Will had got more than enough Aether to maximize his physical stats.
