Hmmm...
JBJ looks stressed (maybe because his voice)
DB looks bothered (maybe because his musicals)
TT looks tired (maybe because his age)
Hugh looks careless (maybe because he still doesn't feel an "official member")
Shanks looks angry (maybe because he does must of the job in the songs and nobody cares)
Phil X looks selfish (maybe because he feels the savior of the "band" caused by Richie's absence)
Everett looks happy (maybe becaus he is the weirdo of all)
So I definitely go with JBJ/Shanks...
