So, I am an HBO subscriber turned GRRM fan. I finished DwD a few weeks after it came out and just had a thought that forced me to start a profile here to see if others agree.
This thought rests on the premise that Jon is Rhaegar and Lyanna's son. I think this has been pretty exhaustively proven.
At the end of DwD, we see that Varys is a Targaryen loyalist who has been starting conflicts between Robert and his allies and later the other claimants to the iron thone while simultaneously nurturing Targaryen claimants to the throne, Viserys and Aegon. However, he seems to also have been keeping tabs on Jon. There is really no other explanation for why Varys wants to protect Ned at King's Landing. He wants Ned sent to the wall so he can return back with an army to install Jon Targaryen as king. The way Varys spoke about Rhaegar in the epilogue was almost worshipful and Varys clearly wants one of Rhaegars sons to rule, whether it be Aegon or Jon.
I was wondering about the same thing, but I arrived at this possibility from a different track
I am doing a re-read of AGOT and in the Varys-Illyrio convo that Arya overhears, we learn that Varys clearly has a plan for Dany and Viserys. In ADWD we find out about Varys' plan for Aegon.
Now why does Varys need Aegon (fake or otherwise) when he already has one Targ claimant in the form of Dany?
Assuming R+L=J, Jon's claim to the throne is stronger than Dany, BUT not stronger than Aegon, because Aegon is Rhaegar's older son.
That's why I think Varys suspects the truth about Jon, and is starting to back Aegon (over Dany) because his claim is stronger.
