Bab 1012: Cap 1010: Too early to know

I was looking at my sister, this was the first time I've seen such a serious expression on her face, but before she tells me anything I feel my head hurting as a life size version of Caitlyn appears in front of me. 

"Elizabeth, are you crazy?" (Caitlyn) 

"You shouldn't make an Illusion like that yet, the weight on his mind..." (Elizabeth) 

"Just so to stop you, it's still too early for him to know about it." (Caitlyn) 

"I don't believe being prudish about these things, sometimes knowing the big picture can be better than seeing just a part." (Elizabeth) 

"There's no point in him learning about it with his current strength." (Caitlyn) 

The two are arguing and I'm worried about what my sister was about to tell me, by her expression I knew it would be serious, but it seems to be something I really don't want to know.
