The thing is... Everyone is basing it on the fact that silver can use ice magic.

Not denying it... But isn't it a bit pushy to have father and son to coincidently learn the same elemental magic.

As of today's chapter... It is comfirmed that silver does not like gray.

Well the name at least... Considering the rogue fiasco in the previous arc... Future and parallel incarnations can exist. Silver can someone from the future or a parallel incarnation of grey.

The only way I assume he could upgrade to demon slayer magic is to slay a demon and infuse ice make with demon magic. Or another theory was that silver is grays son... Though I imagine silver is a future rogue scenario of gray.
