Bethany Joy Lenz Season Two Absences

In the second half of season two of One Tree Hill, the character of Haley was away on a concert tour while the actress Bethany Joy Lenz was away at the One Tree Hill Concert Tour.
Due to the concert tour, Galeotti was absent from the show.

2x14 - One Scene
2x15 - Not in the episode at all :'(
2x16 - In several scenes
2x17 - In a good amount of scenes
2x18 - When Nathan returns home at the end of the episode, there is a message on the answering machine from Haley. Her voice is heard, so I like to say that shes in it, but she really isn't.
2x19 - She makes a cameo appearance at the very beginning. She and Nathan are lying in bed together, then she fades away because she is not with him in anymore. She is seen, so she IS in the episode.

Even if you say 2x19 doesn't count, I feel like at least one of the two (2x18 and 2x19) should count. But I'm unsure whether or not they would both count.

Whenever I list the cast in order of episodes they're in (which I do a lot because I'm really lame) sometimes I put Joy first and say that both 2x18 and 2x19 count, and others I put Sophia first. I spend too much time worrying about this...

Due to maternity leave, some of the upcoming season eight episodes will also have a little less Haley :'(
