Samantha lied to Edwin only because she couldn't tell him all about Excalibur and other information.
Also, she knows how much he respects and admires Bill. If he ever finds out Bill supports Grim Reaper over him and the intentions, he has towards Edwin, then the man would break into pieces.
Samantha would never hurt Edwin and neither will she ever let her father's name get degraded in front of anyone else.
Just like Bill, for Samantha too, family is more important. If the situation ever comes to extreme level, then Bill would be her top priority as he is her family.
"Hmm, got it. So, uncle has no idea about it?" He just wanted to confirm.
"Yes, he has no idea. I would appreciate it if you keep the information of this call under wraps. Don't you ever dare mention this to anyone else." She again warned him.
"Okay darling, won't mention a thing in front of uncle Bill. But tell me one thing."
"Hmm?"
