You can bring your Reflective Journal to the Professional Discussion for reference.

When responding to questions in your Professional Discussion you should refer to the projects in your Reflective Journal to illustrate your experience and demonstrate applying skills in practice. The assessor will frame some questions around specific projects in your Reflective Journal and also ask you questions where you will need to give factual answers and then refer to specific projects to demonstrate your skills.

No, the assessor will not refer specifically to the KSB they are asking about but it should be clear from the question. They may follow up with a probing question if they think you could provide more information.
