The three portraits each have a set of four words followed by a common number of blanks.
Left Portrait: PARTNER_ _ _ _, FRIEND_ _ _ _, DICTATOR_ _ _ _, INTERN_ _ _ _
Center Portrait: DOUBLE_ _ _ _ _, BLANK_ _ _ _ _, BOUNCED_ _ _ _ _, RAIN_ _ _ _ _
Right Portrait: DOUBLE_ _ _ _, SCREEN_ _ _ _, WORD_ _ _ _, HORSE_ _ _ _
<spoiler> This is basically an involved "Match Game."
The matches, from left to right, are: SHIP, CHECK, PLAY.
The skywriting clue gives you the words:
FULL, CLUB, DOG, BUNK
These words act as a fourth portrait, and their match is HOUSE.
Though we don't know the number of blanks at the end, we now have four words that need a match:
SHIP____, CHECK____, PLAY____, HOUSE____

The answer is: MATE </spoiler>
