Well… I know you want to give him a home and get him out of the pet store, but don’t let that be the deciding factor. They will just replace him with yet another bunny once they run out of stock. You cannot save all pet store animals, since the pet stores have an endless supply.
Do you have the money for a second rabbit right now? Two cages, two bowls, two sets of toys, etc? Do you have the TIME for bonding right now, if you’re going back to work soon? Bonding means sessions EVERYDAY in order to get it done and sometimes it can be difficult and take months. Also, many rabbits lose litter habits during bonding (and mine never quite got theirs back even after almost a year of being bonded), so lots of extra cleaning. If you work during the day, Rory will probably sleep through most of it, so isn’t likely to get lonely. So do YOU want another bun, for yourselves, not just for Rory?
If those questions lean towards getting him and you really want to, then go ahead. But, I would suggest letting Rory bunny date for an easier bond at a rescue when you get him a pal.
You can do bonding sessions in the car/bathtub since your place is small.
