He had a brief moment of sympathy for Zwei with how she was killed, but has equally few moral qualms about getting rid of her. He wasn't around to find out that Echo got gutted while Zwei was in control, but he basically has no reason to trust her and knows she's been a danger. He'd be fine with killing Zwei, but has put that out of his mind because he's not really sure at this point if it's possible without killing Echo, and that he's definitely not willing to do. He's hoping they can work out something with either Three or another personae to incapacitate her on a permanent level. However, he doesn't feel quite as close to the situation as some of the others, because his relationship with Echo isn't as strong as other people's. In the end he's more than willing to just defer to what Breeze wants to do with the situation, and isn't likely to voice his own thoughts on the matter unless directly asked.
