Waiting a few moments for the device to produce results from Alex's blood or not, Renand began to stare at the heart which was still beating even though it had not been inserted into the body for years..
"This really is Alex's blood." Clarke stared at Renand with an astonished gaze. "Even the blood continues to flow because there is an active heart, Alex always surprises me with all his cleverness." Praise Clarke.
"By the way, does it really know if this is Alex's blood or not. From what?" Kate asked, a little confused.
"I do have Alex's blood sample, I keep a few drops and I freeze it. If at any time we need, and it is really needed .. I put it in this tool and I put it in the tube on the left." Kate pointed out that there was a small tube filled with blood. "And the right tube of Alex's other blood. From the results of both, tested positive .. That means this is the same blood.", Said Clarke who explained briefly to Kate.
