In the theatrical version of the film "Bright Eyes" the ape refuses to leave her cage and attacks a technician Robert Franklin (Tyler Labine). She freaks out, runs all over the lab and crashes into the boardroom where she is shot dead. It turns out she was protecting her newborn child.
In the storyboards provided by Drummond, it's "Lucky" that's being strapped to a lab table and escaping with "Bright Eyes" help before crashing into the boardroom where he is shot. - filmsketchr
