To evaluate the value of msg.sender when using solidity/assembly's delegatecall:

We start out with 3 contracts:

pragma solidity ^0.5.7;

contract ScratchPadActions {
    event SenderActions(address contractAddress, address sender, address second);
    function relay(ScratchPad2 second) public returns (address) { 
        emit SenderActions(address(this), msg.sender, address(second));
