Summer doesn't officially begin for another month, but most of our favorite TV shows are ready to go on vacation now. Shows wrapping up their seasons this week include The Following, The Flash, Battle Creek and a few others. Of course, following Mad Men's finale last night is an even bigger, as David Letterman turns out the lights at The Late Show for the last time Wednesday night before Stephen Colbert takes over in September. Bungie is releasing a second Destiny expansion with House of Wolves, adding the Prison of Elders, Trials of Osiris and a few other wrinkles to its online shooter. Look after the break to check out each day's highlights, including trailers and let us know what you think (or what we missed).
