It's kind of an oh shit situation but I think if anyone can get help him through it, it's you ... atleast partly.
April is going to be a big month for him but not in a good way. The 1st is his wedding anniversary so he'll probably need to be distracted on that day. On the 5th, though, you might want to leave him alone because that's the day Aves disappeared and he'll probably be in a mood.
I'm bringing all of this up because it's been a year so it's probably going to hit him like a ton of bricks. Next year will probably be better but the first year is always the hardest.
