The second one sounds like Online Drama by BelleDayNight (rated T on FF.net). It's been awhile since I've read it myself since the last time it was updated was awhile ago, but I seem to recall an online meeting with Kag and later a face to face at a Judo tournament. It's also really unique in that I believe the author has two versions up with Kag ending up with a different brother in each.
If it's not I think it's a great fic and BelleDayNight is awesome, so I would highly suggest reading her stuff if you haven't already
Hope this helped!
