Black Hole is initially alarmed, only to realize that he can just suck up the laser beams. As a result, Black Hole starts sucking up Teardrop's blocks, while mocking her for not being able to kill him, all while Teardrop fires repeatedly at him from behind. The only blocks left are the three on her stack. Before he can suck them up, Teardrop jumps in front of it, making Black Hole stop.
