Don't know if this has been here before, but it could be cool if instead of just popping in for the song the other twin stays and chats after the song so it doesn't feel like the other twin was brought in just for the song only to leave immediately. To me it makes sense if they were to leave when the primary twin starts singing a solo song and they wouldn't come back until the next twin song.
#Other twin should stay after a twin karaoke song during the intermission
