Dylan O’Brien is one of the stars of the series, and he revealed some new information about the upcoming third season. According to From Inside The Box, Stiles and Derek won’t have much interaction in the first half of season three. O’Brien said the following about that:
“There aren’t any Stereky scenes so far. But I had an idea for Jeff, that when we do finally meet, and if we have a scene that’s very expositional — like if we come together and something’s going on we have to converge and discuss something — then we should kind of stop at the end of it and before we walk away, Stiles should just say, ‘I missed you.’ Just to acknowledge it for the fans in little, funny ways.”
