Yeah he died the second death
Poor Eliza does have a sad arc, though she's prolly happy she had Alexander as her husband (minus when he cheated)
Yeah peggy was no longer with them
Indeed
MY FRIEND WATCH HAMILTON AND THIS IS WHAT SHE HAD TO SAY ABOUT IT:; -I FEEL BAD FOR PHILIP'S ACTOR! HE CAME BACK JUST TO DIE AGAIN! -I FEEL EVEN WORSE FOR ELIZA. HER SON DIES, HER HUSBAND CHEATS ON HER, AND THEN HER HUSBAND DIES! -ACTUALLY, I FEEL EVEN WORSE FOR PEGGY. SHE STRAIGHT UP DISAPPEARED! -WHEN ELIZA GASPED AT THE END, I THOUGHT, "THAT'S AN... *INTERESTING* WAY TO END THE MUSICAL..."
