Mischief Alex has been involved in:
1) tearing down the initial snake statue in the dd (led by Chris, wearing a hoodie and a beanie, I believe)
2) deliberately touching the snake statues at the art exhibit
3) interrupting the dumping of pink goo into the city's water reservoir (with Julien, Hajime, Aria and a few others, disguised)
4) burglary of two? Thunder corp residences (led by Vanessa, wearing a cut stocking over his head ha ha ha)
5) visiting Tuning Towers (before the increased police presence)
6) tangoing with a bipedal snake statue on the 21st 19th (with banagher and Vanessa, still in progress)
7) wow how did I forget the initial mines visit wherein the sage of the earth called them all in, he went to that
8) batgate 2013 when he bumbled around the city as a bat for a day
9) tainted water induced mirth and bumbling at a bar (with Arthur, John, and Ravindra)

And more everyday stuff:
1) fangs that were recently noticed by his rig partner and brushed off as Halloween festivity
2) sudden paling of his skin
3) if he isn't careful about drinking blood regularly, his coloration (skin, hair, eyes) starts to fade
