Upon reread, I just noticed something really interesting about Tsukishima this chapter:
Its as if he was "teaching" Ichigo things. Why?
1. He did not attack others. He did not even attack chad when chad blew up the place.
2. He makes no effort to actually hurt Ichigo (and Ichigo is human, its a whole different thing than Shinigami, in spirit form you loose an arm or two and you are ok as long as you have will and power to contain your form, in human form, as shown with Ishida, you get a realistic injury and you are out, because thats how human body works)
3. He actually points out the weaknesses Of Ichigo's current form.
Now my thinking is that Ginjou wants to use Ichigo to take out Tsukishima and Tsukishima is actually a good guy. GInjou an "xcution" most likely have different plans. Notice how Ginjou interrupted the fight the moment he figured out Ichigo is still not "at his full" and how he said about "not letting tsukishima and Ichigo fight for now".
IMO, There might be a few possibilities:
1. Tsukishima is hoping that Ichigo will realize that Ginjou is using it. So we most likely will get TsukishimaVSIchigo fight latter on which ends with Tsukishima making him realize that Ginjou is evil bad man who planned this and Ginjou is putting his plans in motion by then. Tsukishima COULD be some more neutral, benevolent character, who does not want to hurt his former comrades but stands in the way of whatever Ginjou wants to achieve. Having him fight Ichigo and then using Ichigo to do whatever GInjou wants seems logical for Ginjou. It would explain on why Tsukishima hurt Ishida, also(since Ishida was following him and most likely tried to confront him) and why he did no damage at all to Orihime(possibly he is someone she knew). If we look at it this way, Tsukishima seems like a tragic character, screwed over by his comrades and treading on the line of neutrality, not able to actually bring the hurt to his comrades.
2. Tsukishima is actually working for Ginjou (Tsukishima's strange "you should have told me about it" line sounds as if it was directed to ginjou) They are playing bad cop/good cop routine to manipulate Ichigo towards something.
Not to mention that Tsukishima's and Ginjou's names relate and Tsukishma's name relates to Ichigo. Tsukishima is "(holy) moon island" and Ginjou is "Silver Castle"
Now some might say that I am looking too deep, but, IMO, Kubo's strength is in details(you know those little blink and miss things like Urahara using Maggots Nest Prisoners to create Hogyoku, Ukitake recognizing Ichigo's reiatsu or the simple difference between human body and spiritual body that was only hinted upon but makes complete sense when we look at wounds Ishida survived in HM and wounds that took him down in physical world)
EDIT: Anyone else waits for revelation that Ginjou's blade is named X-calibur? :3
