If it's the same guy, yeah. I never really talked to him, but I saw him around on the Network occasionally. Bowtie, insufferably cheerful, mentioned something called a TARDIS every now and again. Honestly, he seemed pretty fucking annoying. Don't know why you're looking for him.

I haven't seen him in months, though, so your best assumption right now is that he's been sent back to your stretch of reality.
