ETA: IF AL requested to see both homes this might make some sense. This could've been one of BC's listings at the time, or could've been referred from the other realtor since BC lived in that area?
Another possibility...AL, "Oh, it's just down the road, hop in my vehicle since I'm parked behind you?" Don't think they were ever at the other house but just drove on by.
