One day Professor B tells student A to stop work on the simulator and write some code that he needs for a consulting project. Student A doesn't need the money and would rather work on his/her thesis, but is afraid that refusing might jeopardize his/her RA position. A confides this concern to C, another more senior student of Professor B.
C reassures student A that Professor B would not penalize him/her for refusing the consulting chore. However, A is not reassured, and asks C to promise not to discuss the problem with anyone, especially Professor B.
How else might A get help with this problem?
What might C do to be helpful?
