It's not irrelevant after the 12 billion years it takes to get there.
It is irrelevant, because turbo-1 never said anything about B sharing his observations with us, nor did he say anything about B travelling to meet us. In general relativity you can choose a coordinate system where two events can happen at the "same time" even though no observer will ever have knowledge about both events, because they lie outside one another's event horizons due of the expansion of the universe.
