Apollo will remember everything, but plot points will be the strongest, since I couldn't be around to play out other stuff. His old!sabra personality was still the same, tho he is vaguely wondering if he should do something about mono's alchohol dependency. (He won't.) Unrelated, a part of me likes to think Mono was the first to start being sacrificed when games got all crazy, derp derp.
Ash remembers EVERYTHIIIIIIING and is way more curious about the Gym leaders Judges than before. Might go find some raptors to train Pikachu with.
Kharg onlyremembers any important plot points pyxis would care enough to note on, but not much else. REMEMBERS PYXIS DIDN'T CARE about his crazy lacerta blood so that was cool. Also, tattoos.
