Hmm. yes (when he was young) The original course of life is Matthew being involved in the underworld where he met Inigo. As you've read so far, Matthew was just fascinated about the community and how everything works. The consequences of being involved in the underworld haunted him until seven years later.
so basically, zoey has long cut ties with silva family. There is ongoing war between inigo and niko. Matthew team up or assist inigo just for fun in this war. then zoey fall in love and got married with matty, indirectly dragging back zoey to the underworld. Niko then used zoey to kill inigo. all these plot twist makes me want to binge read from first chp!
Woww Niko was my #1 suspect woooooo***ww , it was clear to me that matt was helping Inigo but only after learning of Inigos death , i know/knew matt loved/loves zoey so i was conflicted and wondered why he was going for Ivan (on niko side) Now i understand. It was clear from flash back of him dealing with ivan whose side he was on but THIS RIGHT HERE , Yeah . I knew it but couldn't understand a motive as to why and now i have to reread to see if i missed the motive .
