What pretext did Logan use to get to know Nicole better?

He pretended to know Czech so he could tutor her.

After we talked during a get-together at a friends house we realized we were both interested in Czech. Logan has just returned from a semester abroad in the Czech Republic and I was about to leave for Prague the coming semester. So Logan GREATLY exaggerated his Czech language skills and offered to tutor me at Expresso Royale Cafe in the evenings. I didnt learn that much Czech but we became closer friends. Despite the obviously lie about his language skills (which Logan I knew from the first second you opened your mouth), I began trusting him immensely after these sessions -Nicole
