As fun as Targuin getting bashed in could be, what I would like to see is the one thing Tarquin would never get over, just to see the look on his/the reader's face.
Now this'd require some hard work on Rich's half to accomplish, and many fans would hate it, but there's one thing Tarquin would never be able come to terms with, the most ignominious way for him to die:
by getting out-smarted by Nale.
Sidenote: my only problem with Tarquin is that he's getting a wee bit Sue-ish in his ability to get out of any situation, thus far. That and the narrative hoops the comic's jumping through to delay the Order from realising Tarquin and Malack have 'sided' with Nale.
