In all the confusion, Shen could have the two jinchuriki sweep Kiro up without anyone but Hina noticing. But she’ll actually be distracted by Guren. Hmm... what should Kiro do?
Sagiso is gonna let Sound just walk away with all they want over his dead body XD
In truth though I really think Shen bringing in the other Jinchuriki was majorly overkill for this situation. Tayuya herself has no reason not to bail to Oto in the mess either.
