From Halopedia, the Halo wiki
Blake was asked to see to Professor Anders after she arrived on-board in 2531. Blake was against this as he thought he would probably never babysit civilians if he was stationed on the UNSC Prophecy.
Blake was also present on the bridge when the Spirit of Fire arrived at Shield World 0459. When the ship received large amounts of information from the planet below he seemingly became flustered and confused.
