Mentor and course role

Please could I have some help with the R line in this model. Thank you.

C Mentor asked what was my course role

T She could have emailed me directly

F Annoyed

A. I emailed the course leader and said I was confused about the email, I looked through some of the emails, I didn’t sleep well, I prepared a timeline of all of the emails, I emailed the course leader again and explained myself, I arranged to meet the mentor, I emailed the trainee, I didn’t email her directly.

R. ?
