I think it does. Leo was speechless for a moment, unsure how to respond. How did it change things though? the part of him that would always be Marc's little brother wanted to cling to how things were. Because at least how things were meant he wouldn't lose the brotherhood or closeness they had formed. Or their plans, which in that moment felt like the only solid thing he had going for him.
"Oh," was all he said though, his expression neutral as the wheels turned in his mind. "So everything we've talked about, it all just changes like that?" Leo finally found words again. "Do I even get a say here?" He could hear his own voice get louder as he spoke and his dark eyes locked on Marc's, searching his brother's expression for some kind of hint that soon Leo might become an after thought or what they had planned would be tossed to the side in favor of Marc regaining his old life.
