Having taken time to speak with Jacen, Peter had not gone to bed once the patrols were done. There was still the burning need to move, to stay active, that overrode any attempts to even feign sleep for the few hours he could to stay with his wife a bit longer. Leaving Sarah with a soft kiss, and a tiger lily placed on the empty pillow beside her, Peter had gone back out, unsure of what he was looking for until he felt the pang of emotion, and followed it to Luke.
He heard the young man's words, and the memory struck a chord in him, reverberating through his body. A tiny body, broken and battered, tucked into Mantis' arms while Peter had injected his own blood into the boy, in order to heal him and his sister.
Knowing that the memories being called up would be a hundred times stronger for Luke, Peter had waited outside, not willing to interrupt his friend's reverie, and just as unwilling to leave him to deal with the aftermath of that reflection alone.
