It's not in any way optimal, but:
Not sure why this entered my head and is forcing itself out. But somehow flavor text for the thread is still missing.
The reason why some noncombatant characters stay as close to the forefront of the fight as they tend to? Sometimes storywise they are the focus of the fight the enemies target and they cling to a bodyguard as a necessity but not always.. it can be they are brave to fault, curious and concerned for those who they travel with and even if they dont/wont kill anything they want to help (but arent sure how). A sudden scream which distracts an enemy and gives an ally an opening from a distance is handy but the characters arent planning for that... just exploiting it when it happens. It might be something else like a poorly tossed rock which distracts the enemy hey look how bad the attack was hehehe oops forgot the other guy. Princess Michelle is a rousing 8 dex so she can do all kinds of accidental things ;-).
Some of the hybrid warlords are demi combatants and only consider themselves ranged so making sure they stay close to a melee competant ally and intensionaly provoking that enemy in to the blade of there ally rather than providing the enemy nice attacks against them works great or
Even cooler a Wizard might skin it as Arcane (kind of like using cantrips in a fight but even just for flavor) using there powers to distract an enemy or befuddle them cause them to forget the ally they were targetting is there or even physically push them at the right time for them to be skewered on your allies nearby weapon.
4e character creation on the interweb is often mis-characterized as being not versatile... In the here and now with a little imagination this seems just so wrong.
Well, 4e character creation is QUITE versatile, it is just designed to fill a somewhat more narrow niche than in previous editions of D&D.
The devs never intended 4e character classes to represent NPCs at all under any circumstances.
As for this particular meme I think the princess could easily justify some attack powers now and then, slapping an enemy in the face "Oh, how DARE you!", picking up a loose weapon and amusingly taking a (surprisingly effective) awkward swing at something, etc.
