For Anyone Needing Info on how to get Easy Friendship Points from Fenris in the First Act here are some tips:
The Wayward Son quest will give you 30 Friendship points if you:
Ask Fenris to make Danzig talk when you are in the Darktown part of the quest
Then kill Danzig (he'll just sort of keel over haha

)
Pick the "Worth the Risk" option when confronting Feynriel's kidnapper in the cave. Hawke will say go limp Feynriel, or something like that. Fenris will be pleased.
Next, make sure you send Feynriel to the Circle. Don't let him go free. Feynriel won't like it but Fenris will.
Alsoo... Take Fenris and only Fenris to complete the Errant Letter Quest. Talk to Thrask. As tempting as it is to be nice to the poor Templar, if you opt to blackmail him this will give you 10 friendship points from Fenris. If you wish rivalry from just about anyone else bring them along too when you do this. Otherwise just keep it between you and Fenris :-)
ok so that's 40 friendship points right there that are pretty easy as I'm sure some here already know, but if anyone asks, feel free, anyone to copy and paste this info or just pass it along if anyone else asks. These are very tried and true, I've done them several times. There's more too but I'll put them up in a different post. But these are the easiest ones, I think.
