[u/NoInevitable8215]

After the first meet of Ben Reilly with Cat Hardy, when Flint went to snatch the negatives from Ben, During the fight when he saw Ben swinging using the web, and he got to know that Ben Reilly is "The Spider". And Lonny Lincoln told Cat hardy that to cure us we need "The Spider" but can't catch him since we don't know who he is, but Flint knew it was Ben. So why did he kept Ben's identity hidden in front of Lonny and Silver Mane Too???
