You are mixing and combining different aspects into a single question that makes it extremely confusing on what it is you want an answer to.
enclosing in double quotes means that the shell will interpret the contects within if there is a variable. using a single set of quotes means the data within is literal.
somevalue='pattern'
The above in a shell is defining a variable named somevalue. To see the contents of the variable you prepend it with a $somevalue
echo "$somevalue"
will output pattern
echo '$somevalue'
will output the text $somevalue
the same is true for grep "$somevalue" versus grep '$somevalue' from any source
If you open a quote the input handler on the shell will wait until you enter a closing matching the opening in your case it is waiting for "
control-D will indicate end of input, and you will get an error because of the mismatch of the ".
control-C will terminate the echo command.
