Does anyone know who KTAs starting support was for Champions Winter 2012-2013?

Sorry to bother you guys, but I need to know this for a school project. lol.esportspedia.com and lol.gamepedia.com both have Wall and Zero as the support, which means one of them was the mid, but there isn't a way to tell which person played in which role. I'm not able to access the VODs to the tournament, because Ongamenet VODs are only available to subscribers. The VODs in Korean redirect me to their 2015 page and /r/loleventvods doesn't have a thread for the tournament, so I'm in a pickle. If anyone could help me out I would greatly appreciate it. Thank you in advance and sorry for wasting your time.
