To start off, the clone would notice, obviously, the sudden destruction of its current shelter. It would thus be ready to counter attack and knowing Soru, this would involve Taijutsu and probably not even the real one, though it wouldn't matter in this situation. Upon seeing the menacing figure that bashed through the protection, the clone would use some of the chakra invested in it to deliver a kick as well with just about the same speed as the enemy. Though, the being would actually desire physical contact as both would be about half a second from having contact, the clone would use a small amount of charka to use Rocket Feet in order to simply 'push' away the threat away from it. The attack in itself wouldn't be in any way damaging or lethal. However, if this swift counter were to succeed, the clone would pick one of its explosive kunai, a kunai with an explosive tag wrapped around the handle and hurl it just as the enemy would be projected away by the Rocket kick. If it were to hit, boom would go the clone. While remaining in the hypothesis that this counter was highly successful, the clone would have another kunai summoned to charge at the 'other' Soru the real Bakou would have felt moving by the effects of hiding like a mole toward a direction before vanishing, likely taking a hiding spot on a tree or a water source.
The real Bakou would notice the sudden explosions made by the real Soru and wouldn't mind them at all due to his ability to pretty much cancel out nearby explosives that aren't his. He'd also visualize the field through his clone's sight, guiding it so that it could head toward the real Soru despite being blinded by the think Mist. Having used some chakra, its explosive power would be slightly weaker, but it didn't matter all that much for its use would yet to be really defined by the upcoming events of the fight.
