Robin was very interested to see Marian's current abode, and part of him was suddenly homesick for Locksley Manor, where he always thought they would end up-- until recently, that was. But still, there was something so thrilling about making a totally new home together, and when she handed him the key, he could not resist grabbing her up in an excited hug and kissing her soundly before setting her down so that he could open the door.
The shape of the key was a bit more complicated than he was used to, but he got the lock open on the second try. Pushing the door open, he bowed to her, holding an arm out. "After you, milady." He considered carrying her across the threshold, but being that she had requested that he consider them betrothed yet, decided against it.
At first.
But in the end, he could not resist, and swung her up into his arms before walking into the room.
