I amped Gram yesterday and he was also controlled to kill someone. That was also announced in the thread.
You are way too focused on Adam because of your personal reads on him. Everyone else town reads him.
Also, if I was scum and did know that Adam shouldn't technically have any kill shot left because he just used on on Pot, then why would I knowningly announce it in the thread - if not to avoid any future confusion since I already had a bad inident with Gram the previous day. Why would I make myself more vurnerable to suspicion by saying my amp actually caused the kill or whatever. Also I amped him and not refill. IIRC, The kill on lethal was a normal kill and if it was my amp then it should have been a super kill.
