He is probably fortunate in that he is a QF staff-member and any unfair targeting of him would/should put the QF/EK alliance under stress (if QF has any cojones).
So if they try to blame it on the FO they are thus effectively saying QF pilots are no good and QF should counter this.
Will be interesting to watch the blame-appropriation but again I hope the FO is looked-after by people outside of the EK system where his well-being is, I suspect not paramount.
