What Marcel failed to tell Arianna was that he had fallen asleep in her arms even after the promise of staying for just five minutes. However, by a stroke of luck or something - his luck was indeed plentiful that night - he had woken up an hour later and decided to return to the room.
He had successfully snuck back in only to turn and saw Elvis wide awake and watching him. He nearly screamed in fright and placed his hand on his chest to calm his beating heart.
"Where are you coming from?" was the first question he asked him as expected.
"I went out to answer the call of nature," Marcel was close to saying when he recalled the toilet was right over there and this isn't the stone age where he would find the latrine outside the house. Yep, Elvis would have caught him straight away.
