Mira vs new team 7 question episode 38 Boruto

[Meowazziel]

In episode 38, we have Mirai vs new team 7.

At some point Sarada her shuriken lands on the bridge.
They zoom in on this shuriken and it gives her an idea.

What exactly was this?

Was this because of the sound that the shuriken made when it landed?
That she heard through the sound, that there was a boruto clone under the bridge where the shuriken landed and
that it therefore made a different sound, than it would make if there wasnt one under the bridge?

Or did the shuriken laying on the bridge just give her an idea?
The idea to try create an opener on Mirai through the floor?
Possibly boruto coming from under the bridge helped that idea too.

Around 18:18.

Her sharingan was activated so she could see the clone’s position under the bridge via chakra when she looked down at her shuriken

Good possibility.
