You were injured on a mission you were on with Yamato and Guy and have withdrawn for the time being. When Yamato approached you and told you that all opponents were defeated, you sat up with a painful groan.

When Guy came along and saw your condition, he wanted to help you stop the bleeding, but Yamato stopped him

"No! Stop it!" He says hastily, looking at Guy.

"Guy, get help! I'll stay with her and protect her." Guy nods and runs off to get help, leaving the two of you alone.
