Caradoc had only been vaguely aware of who Octavius Lovegood was: main editor for the Quibbler, which was the publication of questionable validity that had since gone underground to become the literary voice of the Order of the Phoenix. Octavius and his young cousin Luna (whom Caradoc vaguely remembered as being the dreamy blonde with the thestrals) were now the tool used to battle the propaganda of the Prophet, fighting the war in paper and ink instead the bloodier battles out on fields and roads.
Hermione had been in touch with Caradoc to ask him about interviews for all the Order members who had been with the group for extended periods of time, so he was prepared to get an owl concerning that, but had assumed it be from Hermione. Receiving one from Octavius had been a bit weird, but after the events with Rodolphus he had made a point of not leaving his home and laying very low, so the chance to get out (even if it was just to Headquarters) was welcomed.
He floo'd into Headquarters and landed inside the large hearth with a disgusted sound, floo powder and soot getting up into his face. He stepped out and brushed his jeans off, thankful he was wearing a black shirt, and not white. Caradoc glanced around at the empty room, and quirked an eyebrow as he called out, "Anyone home?"
