This one's called "Anak". An alternative title would be "A Mother's Love". Katipunan is CPP (he changed his name after he became communist). He was named after Martial and Philip's dad KKK/Katipunan. CPP and his fam have a pretty strained relationship cuz of the entire communist thing. The only person he's okay with, other than his bro MSK, is Russia who is his godfather.
