A feeling of déjà vu that you have around someone you recently met could be something that's on your mind, dear Leo. Even if you don't have that feeling of déjà vu, you may have instantly felt a sense of affinity or warmth for this person, as though you knew them from a long time ago. Then again, maybe the feeling that comes to you is one of coldness - as though you have an instant dislike for them. Whatever the feeling, you can't let it dictate the choices you make without figuring out where it's coming from. It may be significant, but then again, it might not. Spend some time dwelling on this - you need to figure it out.
