Yes ... communication and team-work is the key. Many years ago, my copilot found a bent compressor blade on the walk-round. He told me, the Captain, and I asked for an immediate engineering assessment which led to a decision for an aircraft change.
Here is a line of communication that that is essential. It is the Captain's responsibility to initiate the correct actions from any adverse report from any information received.
This Captain, although unaware of the initial error, ensured that he brought the flight to a safe conclusion. He is to be congratulated for a job well done and saving the lives of all concerned.
Blame is an emotive word that the legal profession thrives on. All concerned must be thankful for a safe conclusion and I trust that we have all learned from this by improving procedures and inspections ... the best outcome!
