Maybe they'll be like Kanto Team Rocket now, be funny and caring when they need to be but on missions be serious?? Yah, I don't know than. Just seems random, I guess they could have sent them to be involved with Team Plasma, wonder how big of a part they'll have in all this?
Well when TRio have been involved in TR plots in the past, they act like themselves, but kinda like how a person will act when their boss is around. If they had done that for BW, but knocked up the seriousness compared to the past, it wouldn't have been such an odd transition there and back
