edit- Reina just blogged about it, it's not because of her stomach. Her ears were ringing painfully all of a sudden so she hurriedly get off stage to get it checked and stayed away from loud sounds. She's feeling fine now but it seems like she's still worried about it, calling it her biggest fear because she loves music and singing so much.

She really should get it properly checked soon

Sayu talked about Eri a lot during her solo MC, she said Eri is still worse than Maachan. As in both of them being uncontrollable and also their spoiled sweetness

When she went out for dinner with her recently, she asked her where the toilet is because Eri already went there first
ノノ*^ー^) : Go outside to the left-hand side
...but when Sayu followed her directions she ended up in a dead end. She had to ask the shop assistant where the toilet really was. Afterwards when she confronted Eri about it,
从*・ 。.・) : It's to the right-hand side!
ノノ*^ー^) : I know~

Later when they were on their separate ways home Eri sent Sayu a mail saying,
ノノ*^ー^) : Let's have a competition, whoever gets home first wins!
...even though just before separating they both looked at their smartphones to look up the quickest route home and it's obvious Eri's trip home will take at least twice as much time as Sayu's. So Sayu mailed her back immediately saying,
从*・ 。.・) : I'll just say this, I already won. Thx.
Eri's reply
ノノ*^ー^) : I'll just say this then, so frustrating >_< !
At any rate Eri promised to come watch MM's concert when Sayu told her she and Reina will be performing Ookii Hitomi. Sayu's glad she didn't come today because it was too embarrassing if Eri watched her singing that song solo
