He walked into the mess hall, his mind whirring with equations and ideas and theories on what had gone wrong, just like Duranda. Once again he'd stuffed up, this time nearly destroying an entire universe, and he braced himself for any insults that may fly his way. But it didn't happen, the mess hall was mostly empty, but then he heard familiar laughter and he walked silently to the curve of the mess hall. When he peered around the curve he saw Sheppard, Teyla and Ronon laughing, just like they did with 'Rod'. He felt his heart wrench and hope disappear in and instant. He spun on his heel and left, un-able to bear it anymore. They wanted Rod, they liked Rod; Rod was cool, Rod was nice, Rod was funny. Nothing Rodney ever though he could be, it just wasn't who he was.
He headed to the west pier, the place he went when he wanted to think or be alone, no-one had ever found him there as it had not been fully cleared by the exploration teams; but that didn't stop him. He made his way to the very edge and sat down, hanging his feet over the edge and staring off into the darkening sky.
Rodney sighed heavily, and hung his head, shame filling his every fiber, shame and regret. Shame; for all the mistakes he'd made, all the lives he'd destroyed. Regret; for allowing himself to believe he had made friends here, for allowing his shields to fail. Well, he wasn't going to let that happen again. No, never again.
As Rodney sat there, once again staring at the darkening sky, his shields went up again, and this time he made sure there was no chance anyone would break through them again. Not a single crack, not a single fracture.
As he left the pier, he was no longer fractured; he was in shards.
Summary: They didn't care to see what was happening right in front of them, and he can't take it anymore. Spoilers up to 'Phantoms'
