what if it oliver queen son in the grave on arrow

I know it a macabre thing to do but I could explain why he would break his vow not to kill. He would have been hot full-blown cry because he was just getting to know the kid. Barry could have met during the crossover episode and that could explain why he went the funeral. He can put him in the pit because how would you explain that to the mother side of the family.That's why I it his kid that in the grave

That would makes sense and as to why Barry did not show up. But, I think it would be cool if they did the Connor story and maybe his Son ages fast through some buff.
