[What Bruce offers may be surprising, considering what most believe his personality to be. And in some ways, its delivery (to the point, blunt) runs parallel with these impressions. But it highlights his concern for his fellow hosts, his fellow broodmate, when he says:]

You have your broodmates to lean on, if you ever think you're going to lose control again. I know you're afraid of harming them, but we'd be willing to offer our strength of mind to you if you needed it. I'm willing to, it you think it would help.

[He may do it anyway, whether or not Shiro really asks for it.]

A clearer head and focus may be beneficial to you in the long run, as well. [Not that Shiro may not already possess such attributes, but one can always improve.] A strength of mind over external forces, control over stresses such as anxiety and pain. I'm still willing to spar with you to aid in its practice.
