Just like Finn, who sought Penny because she was the only person he thought could help him, Nina also had someone she wanted to confide in. Although she didn't call Lily to come over, the latter just visited her. After a lot of teasing from the observant Lily, Nina eventually confessed what was bothering her.
"No, I don't need him to ask for my permission… that's not the reason. I'm not that shallow, Lily." Another deep exhale escaped Nina as she shook her head in distress. She had just told Lily about the situation at her place, particularly about what Nina had been doing.
"If not that, then why are you avoiding him?" Lily's face twisted in confusion. "I'm confused here, Nina. First, you said your boyfriend kissed you out of nowhere, and it felt strange. Then, right after that, you just started to avoid him. Make that make sense."
