In Dragon Age 2 can you get all of the companions?

I was wondering in Dragon Age 2 can you get all of the companions?

Also I'm worried about losing any of them by saying the wrong thing what should I do about this?

Also why did they change the look of Isabella from Origins?In Dragon Age 2 can you get all of the companions?
You will end up losing 1 or 2 at the end. Other than that u cant from what I've experiencedIn Dragon Age 2 can you get all of the companions?
With the latest patch you can potentially keep them all. You have to max them out on either friendship or rivalry depending on the choice you make at the end. For example you need to have Fenris maxed out either way if you support the mages, otherwise he will side against you. Remember that Rivalry isn't a bad thing, if it is at 100% your companions will stay loyal.



Isabela was a minor character in Origins and didn't have a very unique design. They wanted to make her more special and consistent with her back story for DA2. This is why they changed her. I actually don't mind, she looked kind of old and worn out in origins.
