Present day- Spencer is packing for New York, I added a little Hanna & Caleb part you'll see why.
'yes the flight is booked for tomorrow don't worry' Spencer said on the phone to Hanna she hasn't seen her friend for a few years but when they talk it's like no time has passed, Hanna was so excited about the wedding and Spencer knew that Caleb would be loving every minute of his fiancés happiness.
New York - Hanna and Caleb's apartment
Caleb had just hung up the phone after talking for a few minutes he was talking to Toby they had stayed in touch and Toby was planning on flying over for the bachelor party
'who was that babe?' Hanna asked
'Hanna please don't be mad but it was Tony I've invited him over' Caleb replied he wasn't sure how Hanna would react but he knew her anger wouldn't last long.
'what? How do you think Spencer will feel?' Hanna said with shock she knew Caleb and Toby were friends but she didn't think they were this close.
'sorry Han but it's been five years I mean it's half a decade' Caleb's idea of trying to win the argument failed as Hanna stormed into the bedroom.
'Hanna come on surely you agree with me, is the wedding still on' he said walking towards the bedroom
'yeah of course and your right i'm just worried that's all' Hanna replied walking up to Caleb and putting her arms around his neck.
'it'll be okay o promise' Caleb said giving Hanna a long kiss on the lips.
part 4 is over and part 5 is the real start where Spencer & Toby finally see each other after 5 years.
