Stefan seemed to accept her answer, and Elena was grateful for that. While a part of her wanted to tell people how happy she was with Katherine, it was far from an accepted lifestyle and she knew that it never would be. It wasn't something she could just go telling people. That was how she justified this lie. Even better, he didn't press the subject of who the friend was or why she kept checking her phone for this friend.
"I guess so," Elena replied. "But be careful. If a Klaus or someone equally as evil comes looking for a human Stefan, he might try to go after you." She really didn't want anything to happen to any of the Stefans, or even the one back home.
When Stefan opened the door, Elena walked through it. "Thank you." He was even chivalrous for friends, though that didn't really surprise her. Stefan was a very kind and caring person. That was why she felt so bad about being unfaithful to her own Stefan back home. He didn't deserve that. She shook those thoughts quickly. "I could go for good food," she replied.
