I think what Swan is trying to conclude to you is that his/her emotion is based solely on his/herself, coupled with those who benefit or mean something to him/her.
Ex.
If my sister were walking down the street, and I saw her get murdered, I'd have a serious problem with it, and act accordingly.
If I saw a random stranger get murdered, well, that's just it. I would probably get away from all cross-fire as to not cause any damage to myself, and get all of my loved-ones out of the way, if they were with me, but other than that, I simply wouldn't care.
That's only what I'm assuming he/she means.
