Finally, I had understood what sort of past did Vicar's mother had with Sir Allen. My assumption was right after all that Aliss and Vicar were indeed siblings. I do wonder why Vicar acted as a childhood friend even though he knows the truth.
"Why don't you tell Aliss the truth?"
"It's better that we remained as a childhood friend..." Vicar said that with a smile on his face.
"You are siblings! Being friends is better, is something wrong with you?" I don't understand why he wanted to hide it, if it was me I will tell Aliss for sure.
" You don't understand..."
"I think I understand this situation really well Vicar."
"Didn't you listen to the whole story..."
"I did listen to all of it."
"If you did, you should be able to know why I prefer to be known as Aliss childhood friends rather than her brother." He said to me.
