I was thinking the same but considering how selfless sion is, Pavel believes it is the best option. I think both are having anxieties towards the future after what happened. It no longer follows the past. I do hope they can prevail through this uhhhhggg
I think it's because he didn't want to worry Sion and make things even more complicated as it already is. But I do hope he eventually tells Sion everything—from the actions his committed, like the "betrayal" he did during their shared past life.
why cant pavel just confess the truth to sion? i believe it may solves so many issues like sion’s anxiety and plan for the future better
