Heh.
This is a wild guess.
Your original clue is tearing me apart...
I will go rampant
The start and end of a deed
But where is the coat?
"I" will go rampant...
Makes me wonder if you mean "Eye" will go rampant...
And things like eye flus can be rampant...
The start and end of a deed...
I assume that's "d"... because start and end of deed both end in "d"...
But where is the coat?
That's throwing me off.
But there is something known as Coat's Disease, which is related to the eye.
So two things seem to potentially point to an "eye" if we're going way out there with clues.
The deed, I assume is "d" - but can't piece it together.
So... Wild guess.
Are you the "EYE" (look) icon?
It's not alive.
It travels with Alex.
It's in the open.
Avid players know where to LOOK.
Indicating using the EYE/LOOK icon?
So the eye/look icon?
Is that you?
