Lol, dude, it took me, like, 45mins to do my Keep and then another 15mins to watch the recap cutscene it provides at the end of it all (voiced by your favorite dwarf...). It was a great trip down hundreds of hours of memory lane. Three DA:O playthroughs and two for DA2, lol. I still highly recommend them unless you sold your 360.
Oh, you went with default world state? Morrigan will have a natural human child with the Hero if they were in a romance; she will have a god-demon-ritual child with the Hero, Alistair, or Loghain, if the Hero chooses so and depending on who is still in the party/alive at that point; or (as the default world state for DA:I is) everything can be refused and she will have no child.
Cassandra became my Divine. I also pushed her into it, mainly because I disliked her and wanted to make sure Leliana was around to play as/with in future expansions/games. She was a team mate in DA:O, and romanceable (but she used to be SOO goody two-shoes!).
Haha, yup, Morrigan and Flemeth lived in the Wilds together for most of Morrigan's life. Flemeth sent her out with the Hero of Ferelden to see the world before she was planned to come back and be taken by Flemeth, so she would be a more well-rounded individual (Morrigan wasn't aware this was the intention until further on in the journey, where her personal quests involve stealing Flemeth's grimoire which gave her the power to take Morrigan, etc. etc.). There's a lot of shit in Dragon Age
