The collaboration stages continued on the sixth episode of Mnet's 'MIX & MATCH,' which aired on October 16.  Although Lee Hi and B.I seemed to have had a little bit of tension after pairing off in the last episode, she and his team did an incredible rendition of 'Frozen's "Let It Go," putting his team in first place in the vocal portion of the competition!

San E said, "I like picking on things, but it was really fun.  The third performance was the best," showing his favorite was the "Let It Go" performance as the first two aired last week.  Tablo said, "I think this was better than other 'Let It Go' covers," and pointed out that the new member, Hong Seok, was not a good dancer.  Still, he complimented them on their cool performance.  GRAY and Simon D likewise pointed out that Hong Seok was not very natural on stage, the latter saying, "I felt a bit like Yang Hong Seok did not match."

Yang Hyun Suk stated, "Among the three teams, this was the most superb arrangement.  It seems to me that Yang Hong Seok's body needs to get used to going slightly with the rhythm for this kind of music."  The team garnered a total of 460 points, coming out in first place for the vocal match with Bobby and Kim Jin Hwan's team following.

In the dance portion, the trainees danced to '90s music as three teams.  Afterwards, two of Jin Hwan's team, Song Yoon Hyung and Jung Jin Hyung, were up for elimination while in Bobby's team, Goo Jun Hee rather than Jung Chan Woo was chosen as another nominee for elimination. Out of the three, two would be chosen.  In the end, both Song Yoon Hyung and Jung Jin Hyung were eliminated.  

Touchingly, the members all shed tears as if they personally felt the pain of elimination. Check out the full episode above.
