Adelisa waited for him to shut the door before sighing and saying "I'm not going to blame you this time around." She took a slight breath and ran a hand through her hair. "I understand that sometimes, when you try again, it goes awry. I love Delilah. She's my sister, but even I know not everyone is perfect nor are they perfect for eachother." She smiled softly at Jareth, but her words cut into her just as deeply. She felt like she was talking to a reflection. Everything she was saying to Jareth was what she needed to realize with Grant. They weren't good for eachother, maybe just as toxic as Jareth and Delilah (to a much less theatrical point that is). 

"I wanted to thank you for the other night by the way. You are much more than just a band rival and my best friend's ex. I just… I wanted to bring you out here because this toxicity needs to stop. It's clear you two don't trust one another and whenever you guys get together neither of you are bettering yourselves. Delilah wants to be on this trip. I'm not saying you should leave because we all need to get over whatever is going on between all of us. You two need to work this out and be civil, atleast, until the end of this trip. Getting back together though? That would not be the best idea." 

She talked to him civilly because she wanted this to end. She wanted this vacation to be fun. She wanted to forgive rather than to forget. Forgetting and running away didn't help her before, so maybe forgiving would be easier.
