Fortunately for her, the door she happened to fall into belonged to one Galen Marek. And luckily for her, he'd heard the thump on the door and went to investigate. He wasn't quite prepared for a girl to sort of slump towards him, but he reacted quickly, catching and supporting her.
It took Galen a few seconds to figure out who it was. "Ahsoka? What are you-" Then he saw the condition of her feet, and the tear tracks on her face, and uttered a string of swears in several languages, some of which Ahsoka might recognize. "Not a word," he told her, holding up one finger to shush her, "until we get you inside and those feet bandaged up." Without another word he scooped her up and carried her into the small kitchen in his house and placing her down gently in a seat, making sure to keep her feet elevated.
He'd cleaned and patched up his own wounds on numerous occasions. Wounds like these simple cuts and the wear were fairly easy for him to fix. Finally, when he was finished, he pulled up a chair, swinging it around and sitting down, legs splayed on either side of the back of the chair. He let his arms rest on top of the backing, and his head atop his arms. "So." His eyebrow quirked up. "Not that I mind the visit, but do you want to tell me what spurred it on?" He didn't mention the tear tracks or the condition of her feet.
The truth was, he had an idea about what could have caused this. But he didn't want to assume.
