Gabriel ended up walking back to the reception and saw Castiel and Dean cleaning up. "Castiel... can we talk?" He asks him. 

Castiel was playing with Erin when Gabriel had come back. He looked over. "Where have you been? W-Where's Sam? We've been worried..." Castiel looked behind Gabriel to see if Sam was with him. "He left, Cas..." Gabriel admits. "He- we- us- we had a talk.... I-I think we're a thing?" He says and saw Castiel's eyes light up. "Really?" He asks. "Sam Sam!" Erin says and claps. Gabriel gave a small smile to Erin. 

"Do you guys need help cleaning up." Gabriel asks Castiel. "I mean... we already have everything mainly put away." Castiel says, seeing Dean walk over with some table cloths in his hands. 

"Gabriel." Dean says. "Dean." Gabriel returned. Gabriel helped them clean up and put stuff away with them. Castiel and Dean headed to the car as they saw Gabriel talking to little Erin. "Gabriel, it's time..." He says. Gabriel frowns and kissed Erin's head. "Gonna miss you little, monkey..." He said to her. Erin giggles and cooed at him. "Bye bye!" She says cutely. Gabriel waves. 

Dean got her strapped in her carseat. Gabriel looked at Castiel. "I had a good time, Cas... I wish we could do it again." He tells him. Castiel nods silently as he was thinking. "At your and Sam's wedding?" Castiel teased. Gabriel chuckles and shrugs. "You never know..." 

Castiel and Gabriel share a laugh. "I-I still wanted to talk to you, though..." He tells Castiel. Castiel hums. "What about?" He held himself and told Dean to wait a minute in the car. "I wanted to apologize for the times back in high school... I was a jerk and didn't help you. I missed you so much when you left with Dean. Do you think you could ever forgive me?" He says. Castiel stares at Gabriel. "I- why say this now? Out of all times?" 

"Because I felt guilty about it." Castiel hugs Gabriel. "I love you, Gabe. Now go win that big heart of Sam's. You deserve some love besides mine." Castiel kissed his head and messed up his hair like he used to do to him. Gabriel smiles. "Thank you, Cas." He says and went to his car, waving a for sure goodbye this time. Castiel returned it. He got in his car with Dean. 

"Everything good?" Dean asks Castiel. 

"Yes." Castiel says, smiling. They then drove off. Gabriel laid his head on the steering wheel. "I'm okay.... I'm... free." He mumbled and smiled to himself. "I can love again..." He says and lifts his head up. "To a new life, Gabriel." He told himself. "Here we come."
