I'm assuming that by the "tattooed man" you mean,
Lindsey MacDonald 
...
Lindsey appeared as a nameless, Wolfram & Hart lawyer in the very first episode of Angel ("City of..."). We all waited patiently and finally, Lindsey McDonald showed up again in "Five by Five." We found out that Lindsey was definitely one of the bad guys when, after Angel foiled one of his court cases, he hired Faith to kill him. His plan went sour when Faith had a breakdown and wound up a guest in Angel's home. Lindsey then brought the matter to the police department, when he told Kate that Angel was hiding Faith. In "Blind Date" we found out that Lindsey has a soft side. When he found out that a blind woman who his firm had just defended, was going to kill a group of children. Lindsey went to Angel and asked for his help in saving the children. At first, Angel was skeptical, but he did lend his help to the frightened lawyer. Lindsey risked his life by going against Wolfram and Hart. Lindsey did do the right thing, by saving the children, but when a new offer arose for him at Wolfram and Hart, instead of walking away from the corrupt firm, he took it. In the season finale "To Shanshu in L.A.", Lindsey aided the firm as they brought a demon, called Vocha, out to destroy Angel and his friends, Cordelia and Wesley, and to perform something called the raising (in which they raised Angel's sire, Darla). In a final battle with Angel, Lindsey suffered a major loss...in hand, when Angel chopped it off in an effort to keep Lindsey from burning a scroll that contained Angel's prophecy and also Cordelia's cure.
Eve -- the flat faced chick? . . . she's Angel's liaison to the senior partners at Wolfram & Hart. That's about all we've seen with her so far . . . well, aside from last night when she climbed in bed with Lindsey.
