Gabriella didn't think that transferring to Caltech so that she could take care of her grandmother would bring anything other than just leaving her and Troy slightly less (only 66 miles less) farther apart. The one bonus would be the ability to actually speak to Dr. Sheldon Cooper and Dr. Leonard Hofstadter. She was very wrong, however, when she meets the most beautiful girl. She still loves Troy, and Troy knows that she's bi, so maybe they could make it work.

Sheldon didn't expect to have kids, unless in the (far? near?) future with Dr. Fowler. When a teenage girl shows up on his doorstep, he doesn't what to do except to get a DNA test. Until he remembers her mother.
