In the beginning of the episode,Sonny and Chad run into each other in the Cafeteria and Chad remarks "Sonny,Cloudy,Rainy". He then shrugs while Nico and Grady say " We have names". Then Chad replies " Yea,but remembering them would take effort and interest and...". The thing is he remembered Sonny's name even though they only met a certain amount of time ago. This shows that Chad has taken an interest in Sonny. This foreshadows for episodes in the rest of the series.
