The longer this Tilly-debacle continues, the more I wonder where this storyline is going...
Currently I can only see two ways for this arc to end:
1.: Tilly convinces Hannelore (somehow) that they are indeed a useful PA.
Of course this would make Tilly and Hannelore a not-quite-literal pair of siamese twins. But to what end? What's the goal here? Is there an interesting story ahead, that I just fail to see? And also, will ALL QC characters just accept Tillys nerve-wrecking behaviour? In case of Faye I highly doubt that and I think Dora isn't too fond of them either. So, for me, I just don't see how Tilly would fit in with the rest of the cast, and also I don't see anything interesting for them to do.
2.: Tilly fails (hopefully).
But then what? It has already been pointed out that Tilly seems to be here to stay, but with what function to fulfill within the comic? Will they become just another stray the QC crew adopts, after they get fired? (Because, just transferring them to a new... "victim"... would remove them from the comic, wouldn't it?) Will Tilly, as others have suggested, put their skills to use for Dora or maybe even for Faye and Bubbles (which in any case would require a radical change of attitude on Tillys part... if they want to live...)? I don't know, and to be honest, I don't find any of those scenarios appealing.
Any thoughts on that?
