Tucker has shown distrust in Felix since his introduction.

While Tucker was surprised in Felix's reveal it only furthered his distrust.

His fear was the fact the he has been told since Season 8 (and nonetheless by Sarge) that he is a good soldier. He knows Felix is better and his fear is that all of his training is worthless and the testing grounds also exploit Tucker's dislike of Felix and Locus.

He's simply afraid that with everyone looking up to him that he will fail and his reputation as a good solider with fall.
