I think Ulrikkkkkkaaa is infuriated because she knows she can't actually send the naughty child to the naughty step in this situation as any normal parent would do, or indeed as Supernanny would recommend. It's a situation C4's Supernanny would find intolerable - the naughty child is allowed to continue with her behaviours with no sanctions possible.

Vanessa hasn't had to tolerate the naughty child for as long and is there for a purpose - to get back on TV (presumably), so is ignoring/placating the naughty child insofar as is possible to avoid any conflict.
