Empty row, especially on flights with a light load. Most flights are made up of 2 or more passengers traveling together, so they are unlikely to select separate seats. If the seat configuration stays as is, the middle seat picker would graciously offer to switch seats, so OP and the daughter can sit together; while the middle seater would then sit in either window or aisle.
The middle seat picker knows exactly what he/she is doing.
