EW did he just put his finger in his mouth?! That wasn't really what he was asking for!! He was kind of in shock for a minute, but took a gulp of the water and stuck almost a whole breadstick in his mouth.

"Thanks for saving me," Tsuna managed to tell Gokudera after the bread stick. He was kind of scared of the salad now.
