Points to get with her: Talk to her at Stuart's party and compliment her, but don't further talk to Peter. Talk to her at the hike, then help Rachel. At the camp, help with the cooking and have spices packed from the minigame before the camp. Finally, make a funny quote about your night watch duty.
But maybe you're missing points with Peter instead? You can get some by talking to them at the party, talk to him further about politics, talk to him at the lake and about the game, talk to him at the hike and then do the wood chopping task at the camp.
Should be more than plenty, even without suitable traits, but if you need some more points with either, avoid being too athletic.
