Can a model enter base contact with an Impersonation Marker to automatically reveal it?
There's a line on the Wiki that would imply yes
"The Impersonator reveals automatically when he is in base contact with another figure. " But it doesn't mention another model forcing it in there.
If it does get revealed, if the enemy model is ending it's 2nd movement in base contact what ARO's are possible at that point? CC? Shoot before it gets there?
