Alex had arrived quite awhile before Dot and had just let himself into Eric's apartment to make himself at home as usual. He was still amused by the whole situation, chuckling when he heard the knock on the door. He gestured for Eric to stay where he was as he got up to answer the knock, the smirk on his face when he opened the door to see Dot.
"There you are! Come on in," he pushed open the door wider to let her in. "Make yourself at home, Eric won't mind in the least."
