Shameless self insert here, but I absolutley loved the Metal Virus storyline in the IDW comics. And I was always thinking of ways I could squeeze Seven into the story and the effect that would be had. So as a synth, she would be immune to the virus, as other bots and the like are; but known to few is that she 'dabbles' in engineering stuff. Sonic in his tired state of mind goes to visit to see if she has any insight on how to deal with the virus, but in his bonehead train of thought, somehow managed to link her and what she does to Eggman himself.

She didn't take kindly to that, naturally. But, hey; gotta be professional.
