Interestingly, either interpretation points to Roy being listed as level 13 now. If he was level 12 at the time of his resurrection, we could list him as level 13 now based on his having accrued enough XP to do so. If he was level 13 at the time of his resurrection (that is, level 14 at the time of his death), he would not have accrued enough XP to level to 14 based on the encounters we've seen.
