During an intense fight against the infected, one of them had a saw and was chasing you, cornering you as well. In an attempt to defend yourself, you tried to push the metal blade away with your knife but broke before you knew and your forearm slipped on the way.

"The hell?!" But you forgot that Leon, your partner that didn't know you're a past experiment, was right beside you, shocked.
