the part you quoted from the json file would already be the next part after talking to Anna about Adrian finding her page and then in that talk making the decision that Anna will seduce Adrian (sharing route)
(2805 = we-need-to-talk-about-adrian)
(2806 = anna-will-seduce-adrian)
If you just want to enable telling Anna about Adrian finding her page search for:
{\"rid\":2805,\"type\":{\"class\":\"ValueBool\",\"ns\":\"GameCreator.Runtime.Variables\",\"asm\":\"GameCreator.Runtime.Core\"},\"data\":{\"m_Breakpoint\":false,\"m_IsEnabled\":true,\"m_Value\":false}}
and exchange that for:
{\"rid\":2805,\"type\":{\"class\":\"ValueBool\",\"ns\":\"GameCreator.Runtime.Variables\",\"asm\":\"GameCreator.Runtime.Core\"},\"data\":{\"m_Breakpoint\":false,\"m_IsEnabled\":true,\"m_Value\":true}}
