We realized, after a short time, that you probably weren't able to get back on. It was cool. Sumire did, in fact, make it safely out of Steel Canyon. We tried doing that Vahz mission I had with the two of us (her SK'd to 11), but it was too rough for two single-target damage dealers.
So, after we both died, Sumire had to go anyway and I went off to start on a Clockwork story arc. Managed to solo two orange CW bosses in two different missions (though the second one took a death and getting some more Defense Inspirations to defeat), so that was pretty cool.
Hope to see you back on soon, though.
