Allen doesn't like being touched... But Mike doesn't care! Pretty sure the only reason Allen hasn't punched Mike yet is he knows Mike just really likes him... Or he's afraid of how hard Mike can punch back with his bionic arm. Or how hard Daniel can hit. Or maybe he actually likes Mike... hmm...
lol, Allen belongs to my awesome friend;
