Greg being 38 in LLC is more of an observation. Steven is twelve at the start of series; in AILD, he's fourteen, and Pearl's comments peg Greg at fourty. GG/LLC was two years ago in the show, so Greg would logically be thirty-eight.
Time to butt in on conversations that don't concern me in the slightest:
Steven was not 12 at the beginning of the series, many people believe he celebrated his 13th in the episode "So Many Birthdays", but that is not true; he celebrated the Gems' "birthdays". While it is true he did age up and down in the episode due to his mental state, he did revert back to normal in the end, and thus he did not actually age.
"Mirror Gem" is at the start of Summer, and Steven's birthday is on August 15th, near the end of Summer. If he was really thirteen at the beginning of the series, he would've celebrated his FIFTEENTH birthday in the episode "Steven's Birthday".

But only a few months passed between "Mirror Gem" and "Steven's Birthday"? Malachite was formed for months, not over a year. Peridot says it took her months to stop trying to kill Steven, not over a year. They reaffirm time and time again that only a few months passed since "Mirror Gem" up until that time; you have to remember that time passes differently for us than it does for the characters. If you want more proof in a Reddit AMA Rebecca confirmed that, at the time of "Change Your Mind" almost 2 years has passed since "Gem Glow". Not 2 years have passed, but almost, therefore he couldn't be 12 at the start of the series as if he were 14, because 2 years would have had to pass.
No?? You're missing the second half of Season 1 and most of Season 2, where the seasons change from Summer, to Fall, to Winter, then Spring and back to Summer again. They literally celebrate New Years in "Maximum Capacity", way after MG and way before "Jail Break".
