Klyburn makes the connection between the metal in the specialized bullet Lois Lane recovered from Nairomi, Africa and the metal in the wheelchair bomb device of Wallace Keefe used in the Washington D.C. Capital Bombing as being one in the same and developed by LexCorp Industries.

Lois deducted that Clark was simply unable to detect the bomb in time because of the lead.
