Or at least get him to re-do some of the passages that just sound reaaaaally weird, where he puts on random voices and/or reads it in an odd manner. There's a passage on a Venus mission (the archive?) where he reads something sent by the cryptarchs in a horribly awkward voice. Either get him to read it as per normal or insert a message voiced by a different VA who can play the part of a cryptarch. Just one example. I don't mind him at all, just some of the lines.
