Alex, just drop the act already.
After the whole act of your bickering was given away when you messed up accounts and replied to yourself, you "revealed" the prank, but was the prank supposed to be funny? And then you tried continuously to explain what is going in on like 3 different threads, it seemed you were just embarrassed and desperate to come up with excuses. Even the story froggy mercifully shared didn't help your conscience.
Moreover, you might be in some private clinic, with all imaginable connections and benefits. But just so you know any standart hospital in Europe has rules about visiting a patient who's about to undergo an operation. Except for paperwork, staying over for the night is not allowed, except for parents or a guardian. But "Chris" just randomly did when he missed the train? You slept on the same bed at that? You mentioned your constitution previously, now let's keep in mind two grown up men and hospital bed.. hm they are not even queen size.
When someone asked who's Chris, you answered "just a friend I made" (?!) I mean you could mean you made it few years ago given he knows you all so well and even travels so far away for you, but most likely you would phrase it differently, so sounds suspicious.
And first he needed to catch a train home (you might have mean a hotel I guess?), but now he doesn't know where to go when in Germany with little money, again quiet suspicious.
One of the first "chris's" comments was a reply to someone quiery about familiarity of main characters from Honey Troubles and he suggested k's secret. It's bl ok? He has to be quite knowledable to make a suggesting given he's straight. I know some guys also read bl, but your repeatedly emphasise " do not recommend bl" , "he is straight and has a gf", " Wtf Alex reads gay po**". You just give away too much.
