That’s a place where the cement actually meet, it’s more like a cross, where water settled And calcification. I do home repairs for a living, and if you see the cement squares they all meet in the same place there. But that was a good catch. Just in case. If you look where the cement squares meet corner to corner next to the Q - You will see the same pattern.
