fic search: one mccoy/spock and one (possibly)mccoy/chekov

[theoryofwar.livejournal.com]

1) This one will probably be so vague that it hurts. A long while ago, I read a McCoy/Spock fic where something happens to Spock and I believe he mentally reverts back to a child? The main thing I remember is that Chekov replicated coloring book for him. I also think there was something about his fingertips? I'd love to re-read it, and I've searched for a few days, but I can't find it anywhere!

2) The second one is a Chekov one. I'm pretty sure it was Chekov/McCoy. McCoy found out that Chekov wasn't sleeping in his quarters, but was instead sleeping somewhere else (I can't remember exactly where, but it wasn't in his quarters) and I believe someone he once knew, an older man, came to visit the ship and it was an old professor of his? I'm 99.9% sure this fic isn't a figment of my imagination.

Thanks in advance!
