Tangle's Answer Tangle: Friends with benefits, girlfriend, wife call it whatever. As long there is trust and love, I do not care what Sonic and I are. Hell, I can be part of his 6 girls harem.
Sally's Answer Sally: One day... maybe. But for now, I'm going to keep this current arrangement for now.
To Tangle, wife and girlfriend are just labels. But she does respect them. For Sally, she does think about the future a lot due to her upbringing.
