A.N: I've left out most of the trip because nothing significant happens during it. As for the fact that I stated they all are straight, I actually haven't decided whether Siri and Harry are going to be straight or not.
Chap. 13 Fixed
Severus stumbled into the compartment, his eyes wide. He managed to stop moving just short of Black's body. He couldn't believe that Sirius Black, the man who had made his life hell, was curled up in a ball at his feet sobbing. Yet there he was as impossible as it seemed. Why did Remus think that he was the only one who could fix it? Severus didn't even know what was wrong. Thankfully his ever analytical mind immediately began to tackle the problem.
'We know that Black's behavior has been erratic since he found out that Remus and I had become friends.' He thought. "That could indicate anything from anger to jealousy. Yet something tells me that isn't the case. I hate it when my instincts start acting up." Severus looked down at Sirius' trembling form. The man had finally stopped his heart wrenching sobs. "He looks so sad and helpless," mused Severus. Then his eyes widened. "What the hell am I thinking? I'm Severus Snape! I'm not supposed to have a heart. Remus must be rubbing off on me. I'm becoming soft. Gotta be old age creeping up on me." He bent down.
Sirius latched on to Severus when he bent down and started apologizing. "I'm so sorry. I didn't mean to threaten you I was just so afraid of loosing Harry and Remus." He clung to the other man afraid he might storm out. "I promise I'll never do it again. I promise."
Severus couldn't believe his ears. Black was apologizing to him. Suddenly the compassion that Remus had uncovered in his heart came to the fore. He found himself gathering Sirius into a warm hug and began to reassure him.
"It's okay. I'm not angry with you." Severus knew his next words would set the tone for their relationship. His next words however took him by surprise. "Of course I forgive you Siri. You're family."
Sirius Black looked at Severus and responded. "I always wanted a skinny, hook-nosed, greasy, potion making, dungeon dwelling, overgrown bat as a brother. Don't think this means I won't prank you anymore." With a huge grin he jumped up and ran out of the compartment only to trip over Harry and Remus.
Severus looked at the three males and groaned. "What have I done?"
They finally got off the plane and spent a few minutes looking for their luggage. Thankfully nothing had been lost. Remus skillfully herded the group toward the car rental desk. Sirius got the keys to their car and he headed to the parking lot with Harry following close behind. Severus on the other hand appeared to be doing a very excellent imitation of a mountain. In other words he wasn't moving. Remus was pulling on his arm trying to get him to follow Sirius.
"No way. There is absolutely no way I am going to get into a car if Black is driving. I refuse to do it. I'll walk instead" Sev ignored the tugging on his arm.
Remus finally let him go and leaned in. "You can either walk out there or I can carry you out there. Either way you are going to get in that car. Its only a couple hours drive and then were there." He moved behind Sev and started to push.
Siri and Harry walked back in. they took one look at the two men and broke out laughing. They decided to stay there and watch Remus try to get the irate potions master to budge. Finally Severus sighed and took a step forward causing Remus to land face down on the floor. Twenty minutes later they were on the highway headed south little did they know that the two hour trip would take almost three hours to complete.
