Purple headed warrior

[Frank]

I saw you behind me in the Maths lab. I suspect you're a user on the Sinner.

[Delts]

Hmmm, this is a possibility, I remember seeing some purple flashes in windows as I walked by recently as well. I wonder who you are Frank and where you are just now since I also am in maths...

[Hennessy]

I believe this is Frank, or was him at one point. Quite what body he'll morph into next no-one can tell. I head he's been musing on giving up mortality itself recently, perhaps in favour of something more durable, like metal.

[Hennessy]

Wait! A sighting! Proof he is currently residing in this dimension, and probably consuming inordinate amounts of tea.
