Charlie's head jerked up once he saw a young blonde woman step behind the stroller. Now he had never met Claire Littleton in his life, but from Ana-Lucia's description she almost matched it perfectly. He didn't really know what to say, hoping that he didn't look surprised or anything to see her, because he suddenly had an urge of protectiveness when he realized just how scared she would be if he blurted out he knew her- or should've known her. Apparently this was the woman and the baby he had fallen in love with in some alternate reality, and now seeing her for the first time he understood why.
But he bit down on his tongue and cleared his throat. There wasn't any use getting ahead of himself now- Things had changed and this wasn't the same situation. He was still a struggling junkie and right now he realized he was probably staring at her.
"Oh! Hi-" he said, trying his best to look like everything was normal and he hadn't even heard about her in his life before, though his attempts at not stuttering didn't really work. "Cute- cute little baby you have there."
