She knew something bad was going to happen, she just knew it. But even with the foresight that something bad was going to happen again, they still caught her off guard. Luckily she held on to her lipstick, the one that turns into a chainsaw, so she was armed. If anyone needs any protection it could be safe to stay by Kanaya. Chainsaws aren't the cleanest of weapons so she may have a bit of blood on her, don't let that startle you.
