Hey there! No, Akechi will not be able to scroll all the way back. Elias probably keeps records somewhere in his neural network, but that is inaccessible to characters. Think of RSDOS having a limited memory for conversation. He’d be permitted to see, at most, a week’s worth of conversations before they disappear into the ether of Elias’s mind, and nothing from before his arrival to Ryslig/Felfri.
