The anime cut out a detail I quite liked about Yuki
Spoiler for manga version of episode 2:
In the manga when he was running in the minefield and Yuno stoped giving him instructions he looked at the 9th's eyes and realised she kept looking at the spots where she had planted a bomb (in the hope Yuki would step on it) so using her eye movement he dodged the bombs.
Basicly it showed yuki wasn't completely useless
