Things we could have got instead of Alicent and Cole.

I noticed right now that Pact of Ice and Fire does not exist in the show. Also, Jacaerys Velaryon negotiated with Manderly lord that his daughter will marry Joffrey after the war. C'mon, why this pact is needed? Manderly are vassals of the Starks. The main thing that matters is Stark's support. There is no need to make marriage pact with vassal houses. Also, the pact of ice and fire was never completed. Even if the pact says that daughter of Jacaerys must marry Rickon Stark, it could have been changed to any Targaryen prince. Cregan did much to make Aegon 3 the king and he receives broken oath. Maybe that's why Condal did not include these scenes. Jacaerys is overrated, he is not good heir that TB claim. He made valuable marriage pact with vassal house. Also, I did not say about decision Jacaerys will make that nearly ended whole House Targaryen. Instead of seeing how Jacaerys negotiated we got Alicent and Cole.
