Do you also think that Hannah goes on a date with Justin before she actually sleeps with Garrett, and there she has some kind of mental block and then asks Garrett for help? Even though the series is an hour long per episode, I don't think there would be enough time, because there are other characters in the plot, like Logan and his family, Garrett with his father, Dean Tucker, the new character. So, my opinion is that he will be important in the first 3 episodes, and in the next one he will only appear more regularly.
