I don’t know if it’s just me, but…
Liam refound himself, he’s basically everywhere, he’s with Harry for the penis jokes, he’s with Lou when Lou needs to be a menace, he’s with Niall when Niall needs some cuddles, and he’s with Zayn when they need sexual tension.
Louis is everywhere too, with Niall to assure him he worths, with Zayn because they’re partners in crime, with Liam when he wants to be annoying and with Harry because he’s always watching him, no matter how many miles there are between them.
Harry is not so subtle with Louis, always ready to dance and be an idiot with Niall, ready to mimic a BJ with Liam and doing sexy glances with Zayn.
Niall is the little ball of sunshine with everyone. He could be next every other boy and instantly you can see a smile. He cheers up everyone.
Zayn is the wise one. Ready to cause troubles with Louis, to do sexy things with Liam, to party with Niall and to save Harry from stage’s dangers.
Basically if sometimes, during TMHT, they didn’t seem an OT5 (they always are, but sometimes they didn’t seem sooooo close), WWAT is the biggest proof after 4 years they still love each others, and they’ll always be there for each others.
OT5 started strong in SA leg and went stronger and stronger. Maybe we don’t see OT5 every minute of every day, but if you look at the dynamic of the interaction between them, you could see right now OT5 is absolutely strong.
