Well, before, she only pitied Raki because it overlapped with her experience with Teresa. The same can no longer be said, since as you mentioned before, she does appreciate his company, enough in fact, to search for him wherever he may go.

I do agree with you with the transient happiness vs. prolonged stability part. It is indeed the will of the person involved that decides which is more valuable, and I believe its also true in this case, as Raki had said, he would rather die as long as he is with Clare. I do think its more than likely that Raki DOES have romantic feelings for Clare (based on the stuff he keeps saying and trying to do), but even if he didnt before, who wouldnt after what happened this episode.
