This episode is basically a recap of Sai's past journeys, from playing Go in the palace and his eventual suicide, playing Go through Shuusaku and then Hikaru. The second half kind of traces Hikaru's Go journey till the present - the first game btw Hikaru/Akira, set-up of Haze Jr's Go Club, Hikaru letting Sai practise through Internet Go and Hikaru's determination to catch up with Akira. Sai laments to God on why he let him came back through Hikaru and wonders if Hikaru will ever let him play again. (thetvdb.com)
