Even if Tally doesn’t want to admit it, she is clearly developing romantic feelings for David, which means that Tally has to think even harder about how to be a good friend to Shay.

This begins to complicate what loyalty means for Tally, especially considering the fact that David’s feelings matter as much as both of the girls’ feelings do. Because of this, it may not be possible for Tally to make Shay as happy as she’d like to.
