Just as Anthony was about to step through the door and back to his own time, a ball of blood-red flame erupted from the ground and made its home in front of the two versions of the same demon. Crowley's expression was a combinations of being extremely perplexed and also ticked off, however Anthony simply sighed 'oh, bugger', also appearing to be irritated, yet with a significant aura of fear. The creature that stood before the demons was evidently Beelzebub, which was why Anthony was naturally concerned for his well-being, seeing as he wasn't exactly in his good books. In fact, it was quite the opposite, since Anthony had been purposely avoiding Hell ever since the Apocalypse that had begun on that Saturday afternoon. It seemed like such a long time ago now – well, Anthony had technically time travelled, so at the time it was twenty years later – and Anthony just wanted to get back to his angel, and for his life to return to normal without any intervention from Fallen Angels or Princes of Hell (of which Beelzebub was both). On the other hand, he knew he couldn't rush his meeting with Beelzebub, as the demon would likely punish him all the more and keep him apart from Aziraphale. So, he decided to make a little small talk, yet it didn't last long.
"Beelzebub. How… nice *cough* to see you." Anthony was curious, therefore used his opportunity to make a few inquiries after the generic niceties. "May I ask why you brought me here?"
"I thought that wazz obviouzzz – you needed to be taught a lezzzon." Beelzebub replied, his voice still sounding exactly the same as it had in the Apocalypse – like many flies buzzing simultaneously.
"Someone needs speech therapy… Can't you just leave? Kinda busy here, mate." Unable to cope with more infuriating visitors and itching to get back to his normal daily life (not much had changed there, then), Crowley interjected and addressed the Prince of Hell (not Gavin McLeod, that would be awkward since he's Crowley's son – I can assure you Beelzebub isn't in any way related – at least I don't think so…), honestly not giving a damn if his tone appeared incompetent or considering who he was speaking to. In the end, it didn't matter anyway, as both Anthony and Beelzebub blanked him, out of sheer ignorance.
"Rude." The King of Hell commented, and was ignored once again. Beelzebub continued speaking without acknowledging him in the slightest – well, he was addressing Crowley's younger self, so technically he was acknowledging him, but anyway.
"Azz you have guezzed, thizz man iz you in the future. He iz who you will become if you continue dizzobeying uzz. He haz been tortured and had hiz memory wiped, so haz had our orderzz forced upon him anyway." Ah, so that's why he doesn't remember Aziraphale! Anthony had a mental 'Eureka!' moment, as everything fell into place while Beelzebub was talking. Or rather, buzzing. "If you do not obey when you are zzzent back, thizz iz what will happen…" Ending his sentence on a particularly ominous note, Beelzebub seemed to expect some kind of promise of submission or something, as he didn't disappear or carry on speaking. However, Anthony wasn't going to make a promise he couldn't keep. Utter surrender to Hell, becoming their basic slave yet again would ensure that he would never see Aziraphale again. Sure, he ran the risk of being caught and brainwashed, just like Crowley had, but that was a risk he was willing to take for his angel. Besides, there had to be another option, even if it meant stalling for eternity.
"Well I do apologize, but I have a dinner date to return to, for which I am twenty years late!" At that, Anthony simply saluted to Crowley, who rolled his eyes back yet with a hint of a smile playing on his lips, huffed at Beelzebub, and charged through the door. With a bright flash of white light, he was gone.
