Varric, Cole and Solas seem to correspond to Judas, Andrew and Peter respectively.
Varric is in the same pose, has the same colour hair, and is also wearing orange under his armour as Judas.
Solas and Peter are both looking at John / Cass, and both are basically bald.
Then you have the light haired Andrew with the light haired Cole.
Furthermore, we also know from one of the quests shown that Varric gets mighty upset with the Inquisitor if we make a certain desicion.
If we assume that in the end the Inq will have to make a sacrificial decision, perhaps Varric, inkeeping with Judas' suicide, offers to take the Inqs place out of guilt? Just my 2c!
