Tserriednich and Morena relationship
Tserridnich and Morena or perhaps the one who took Morena's entity are probably brothers. I know it sounds silly but hear me out. I will not only support my claim using their appearances resemblance, but also their talent. Morena was able to discover Nen throught the harsh life she lived under the oppressive treatment of Kakin's royals. Meanwhile, Tserridnich lived normally as a prince in the royal family.
But how are they brothers and Morena's mother died two years after she got born?! It's the father who actually important here. Both Morena and Tserridnich show an exceptional high Intelligence and in a way or another might lead us to say both are Beyond's child. But let's be honest, when did Togashi ever made things that simple?! Never.
TThe bombshell is that their father is possibly alive now and we saw him in the mange too. Remember chapter 395?! The phantom troupe flashback?! Togashi allowed us to see two of the criminals and intentionally hid the third one.
Lately, we knew the one who that guy was talking to have died.
and the tattoo guy with them is speculated to be the one who was with Tserridnich.
Why do we think this guy is the one who we saw at the phantom troupe's flashback?! Borksen mentioned a tattoo guy that 4th prince saved from the massacer that happened after Morena became the leader of the Heil-ly family and guess what? this tattoo guy was a member in Heil-ly family that probably was human trafficking. I think so far this is enough to make us understand that the third guy that haven't seen in the flashback is an important character and probably the father of both Morena and Tserridnich.
