A different way
Immediately after noticing the tears on Sil's face, Quinn placed his celestial energy away. The armour that covered his body began to burst into small little particles, and then covering his body with the shadow, he changed back to his usual armour set.
All this might have been an elaborate trap by Sil, and Quinn might not even really be seeing Sil, but he knew the tears were genuine. How hard it must have been for everyone around him when they felt he might never wake up? He couldn't tell, but for Quinn, it felt like no time had passed, yet all his friends had aged.
This included Sil, who looked more like his father than himself. In the end, Quinn inched forward, giving Sil a big brotherly hug.
"It's okay, Sil... you've worked really hard, haven't you? I can tell you've gotten a lot stronger. Strong enough to kick me about anyway." Quinn smiled, relieved that his friend had finally recognised him.
